Following are the measures of the angles given :∠ ABC = 180, ∠ BCD = 180, ∠ CDA = 270, ∠ DAB = 270.

What is parallel lines ?

Parallel lines are two or more lines that are always the same distance apart and never intersect, no matter how far they are extended.

Since AB is parallel to DC and AD is parallel to BC, we know that angles A and C are corresponding angles and angles B and D are also corresponding angles. Corresponding angles are congruent when two parallel lines are intersected by a transversal.

So, we have:

∠ A = ∠ C

∠ B = ∠ D

Given:

∠ D = 3x - 75

∠ B = x + 35

We can solve for x using the fact that the sum of the angles in a quadrilateral is 360 degrees:

∠ A + ∠ B + ∠ C + ∠ D = 360

Substituting the values we know, we get:

∠ A + (x + 35) + ∠ C + (3x - 75) = 360

Simplifying, we get:

4x - 40 = 360

4x = 400

x = 100

Now we can substitute x = 100 into the expressions for ∠ B and ∠ D to find their values:

∠ B = x + 35 = 100 + 35 = 135

∠ D = 3x - 75 = 3(100) - 75 = 225

Since angles A and C are corresponding angles, we know that:

∠ A = ∠ C = 180 - ∠ B = 180 - 135 = 45

Therefore, we have:

∠ ABC = ∠ A + ∠ B = 45 + 135 = 180

∠ BCD = ∠ B + ∠ C = 135 + 45 = 180

∠ CDA = ∠ C + ∠ D = 45 + 225 = 270

∠ DAB = ∠ D + ∠ A = 225 + 45 = 270\

So, we can see that angles ABC and BCD are straight angles (180 degrees) and angles CDA and DAB are reflex angles (more than 180 degrees).

Therefore, Following are the measures of the angles given :∠ ABC = 180, ∠ BCD = 180, ∠ CDA = 270, ∠ DAB = 270.

The solutions of the equation on the interval [0,2π) are x= 5π/6, 11π/6, 2π/3, and 5π/3.

To solve the trigonometric equation sin 2x=−√3/2 on the interval [0,2π), we need to find the values of x that satisfy the equation. We can do this by using the inverse sine function and the periodicity of the sine function.

First, let's find the general solution of the equation:
sin 2x=−√3/2
2x= sin⁻¹(−√3/2) + 2πn or 2x= π - sin⁻¹(−√3/2) + 2πn, where n is an integer
2x= -π/3 + 2πn or 2x= 4π/3 + 2πn
x= -π/6 + πn or x= 2π/3 + πn

Now, we need to find the values of x that are in the interval [0,2π). We can do this by plugging in different values of n until we find all the solutions in the interval.

For x= -π/6 + πn:
When n=0, x= -π/6 (not in the interval)
When n=1, x= 5π/6 (in the interval)
When n=2, x= 11π/6 (in the interval)
When n=3, x= 17π/6 (not in the interval)

For x= 2π/3 + πn:
When n=0, x= 2π/3 (in the interval)
When n=1, x= 5π/3 (in the interval)
When n=2, x= 8π/3 (not in the interval)

Therefore, the solutions of the equation on the interval [0,2π) are x= 5π/6, 11π/6, 2π/3, and 5π/3. These are the exact form answers. If we want to round them to two decimal places, we get x= 2.62, 5.24, 1.05, and 3.14.

The sequence of transformations that maps △RST to △R′S′T′ is a translation of 6 units to the right and 2 units down, followed by a reflection across the y-axis, and finally a rotation of 90 degrees counterclockwise about the origin.

What is the sequence of transformation?

In mathematics, a sequence of transformations refers to a series of geometric transformations performed on a shape to create a new shape. These transformations can include translations, rotations, reflections, and dilations.

The sequence of transformations is the order in which the transformations are performed. The order matters because different sequences of transformations can lead to different final shapes.

For example, to transform a triangle into a new position, we might first perform a translation to move the triangle to a new location, then perform a rotation to change its orientation, and finally perform a reflection to flip the triangle across a line. The sequence of transformations in this case is translation-rotation-reflection.

Sequences of transformations are used in geometry to analyze and describe shapes and to solve problems related to symmetry, congruence, and similarity. They are also used in computer graphics and animation to create 2D and 3D shapes that can be moved and transformed on a screen.

To map △RST to △R′S′T′, we need to perform a sequence of transformations that includes translations, rotations, reflections, and/or dilations. Here's one possible sequence of transformations:

Translation: We can translate △RST by 6 units to the right and 2 units down to get a new triangle that has R at (3, -3), S at (5, -3), and T at (2, -7).

Reflection: We can reflect the translated triangle across the y-axis to get a new triangle that has R′ at (-3, -3), S′ at (-5, -3), and T′ at (-2, -7).

Rotation: We can rotate the reflected triangle 90 degrees counterclockwise about the origin to get a new triangle that has R′ at (3, -3), S′ at (3, -1), and T′ at (-1, -4).

Therefore, the sequence of transformations that maps △RST to △R′S′T′ is a translation of 6 units to the right and 2 units down, followed by a reflection across the y-axis, and finally a rotation of 90 degrees counterclockwise about the origin.

The quadrilateral MNOP if MN=OP and MP=NO, then it must be square (option d).

First of all, since the opposite sides are equal in length (MN=OP and MP=NO), we know that MNOP is a parallelogram. A parallelogram is a quadrilateral with opposite sides parallel and equal in length.

If we were given additional information about the angles of the quadrilateral, we could determine whether MNOP is a rectangle or a rhombus.

Lastly, it is worth noting that MNOP cannot be a square, because a square is a special type of quadrilateral with all four sides equal in length and all four angles equal to 90 degrees.

In summary, based on the information given in the question, we can conclude that MNOP is a parallelogram, but we cannot determine whether it is a rectangle or a rhombus without additional information. We can also rule out the possibility that it is a square.

To simplify the expression, we need to distribute the negative sign to all the terms inside the parentheses, and then combine like terms.

Starting with:

(5x^4-4x^3-2x^2+x-19)-(x^4+5x^3+8x^2+x+5)

Distribute the negative sign inside the parentheses:

5x^4 - 4x^3 - 2x^2 + x - 19 - x^4 - 5x^3 - 8x^2 - x - 5

Now we can combine like terms:

(5x^4 - x^4) + (-4x^3 - 5x^3) + (-2x^2 - 8x^2) + (x - x) + (-19 - 5)

Simplifying further:

4x^4 - 9x^3 - 10x^2 - 24

Therefore, the simplified expression is:

4x^4 - 9x^3 - 10x^2 - 24.

The values of m that will result in a repeated solution for 3x^(2)+4mx+m=0  are m = 0 and m = 3/4.

The given quadratic equation is 3x^(2)+4mx+m=0. In order to find the value(s) of m that will result in a repeated solution, we need to use the discriminant of the quadratic formula.

The discriminant of the quadratic formula is given by b^(2)-4ac, where a, b, and c are the coefficients of the quadratic equation.

In the given equation, a = 3, b = 4m, and c = m.

Plugging these values into the discriminant, we get:

(4m)^(2)-4(3)(m) = 16m^(2)-12m = 0

A repeated solution occurs when the discriminant is equal to 0. So, we need to solve the equation 16m^(2)-12m = 0 for m.

Factoring out a common factor of 4m, we get:

4m(4m-3) = 0

This gives us two possible values for m:

4m = 0 or 4m-3 = 0

Solving for m, we get:

m = 0 or m = 3/4

Therefore, the values of m that will result in a repeated solution for the given quadratic equation are m = 0 and m = 3/4.

Answer: cos B-sin²A = cos²A-sin-B

Step-by-step explanation:

Answer: cos B-sin²A = cos²A-sin-B

Explanation:

Using the double angle identity, we can express the left side of the equation as:

cos(A + B).cos(A-B) = cos A.cos B - sin A.sin B

Now, using the Pythagorean identity, we can rewrite the right side of the equation as:

cos²A-sin-B = cos A.cos B - sin A.sin B

Hence, we can conclude that cos(A + B).cos(A-B) = cos B-sin²A = cos²A-sin-B

Answer: Read the step by step explanation for the answer.

Step-by-step explanation:

We can prove this trigonometric identity using the product-to-sum and Pythagorean identities as follows:

Starting with the left-hand side (LHS):

cos(A + B).cos(A - B)

Using the product-to-sum identity:

= [cos A cos B - sin A sin B][cos A cos B + sin A sin B]

= cos²A cos²B - sin²A sin²B

Using the Pythagorean identity:

= cos²A(1 - sin²B) - sin²A(1 - cos²B)

= cos²A - cos²A sin²B - sin²A + sin²A cos²B

= cos²A - sin²A + sin²A cos²B - cos²A sin²B

Using the Pythagorean identity:

= cos²A - sin²A + sin²A(1 - sin²B) - cos²A sin²B

= cos²A - sin²A + sin²A - sin²A sin²B - cos²A sin²B

= cos²A - sin²A + sin²A cos²B - sin²B cos²A

= cos²A - sin²A + cos²A sin²B - sin²B cos²A

Using the Pythagorean identity:

= cos²A - sin²A + cos²A - sin²B

= 2cos²A - sin²A - sin²B

= cos²A + cos²A - sin²A - sin²B

= cos²A + sin²A cos²B - sin²B

= RHS

Therefore, we have shown that (b) cos(A + B).cos(A-B) = cos B-sin²A = cos²A-sin-B.

Option D, {5+(-1/3)+(-10)}+(2/3+7), would be easier to simplify if we use the commutative property.

What is the commutative property, and how can it be used to simplify expressions?

The commutative property is a property of addition and multiplication that allows us to change the order of the numbers being added or multiplied without changing the result.

That is, [tex]a + b = b + a[/tex] and [tex]a \times b = b \times a[/tex].

To simplify expressions, we can use the commutative property to rearrange the order of the terms in a way that makes the arithmetic easier to perform.

Find the expression:

We are given the expression -1/3-10+7+2/3+5, and we want to know which option would be easier to simplify using the commutative property.

Option D, {5+(-1/3)+(-10)}+(2/3+7), would be easier to simplify using the commutative property because we can group the terms that have like terms together. Specifically, we can group the negative terms together and the positive terms together:

{5+(-1/3)+(-10)}+(2/3+7) = {(5)+[(-1/3)+(-10)]}+{(2/3)+7}

Now we can simplify each group separately. For the first group, we can add the terms inside the brackets using the commutative property:

{-1/3+(-10)} = -10 - 1/3 = -31/3

For the second group, we can add the terms directly:

{2/3+7} = 2/3 + 21/3 = 23/3

Substituting these results back into the original expression, we get:

-1/3-10+7+2/3+5 = -31/3 + 23/3 + 5

Now we can add the terms directly to get:

-31/3 + 23/3 + 5 = -8/3 + 5 = 7/3

The probability that a person from the survey who has a tablet also has a laptop is 0.058, or approximately 5.8%.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

We are given that 62% of respondents have a tablet and 30% have a laptop.

Let T represent the event of having a tablet and L represent the event of having a laptop.

Then, we know -

P(T) = 0.62

P(L) = 0.30

We are also given that 12% of respondents who have a laptop also have a tablet.

In other words, the probability of having a tablet given that a person has a laptop is -

P(T|L) = 0.12

We can use this conditional probability to find the probability that a person who has a tablet also has a laptop, denoted by P(L|T).

By Bayes' theorem, we have -

P(L|T) = P(T|L) × P(L) / P(T)

Substituting the values we know, we get -

P(L|T) = 0.12 × 0.30 / 0.62

To solve for Length, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 5:

200/5 = Length

This simplifies to:

40 = L

L = 40
