Two angles are a linear pair. Their measures are represented by x+10 and 3x+10. What are the measures of the angles

Answers

Answer 1

Answer:

50°  and  130°

Step-by-step explanation:

Linear pair of angles are supplementary, which means their sum is 180

x + 10 + 3x + 10 = 180

4x + 20 = 180

4x = 160

x = 40

x + 10 = 40 + 10 = 50°

3x + 10 = 3(40) + 10 = 120 + 10 = 130°

From nose to tail your first dog is 5 feet long. Your first dog is the length of your second dog. How many feet long f is your second dog

Answers

According to fraction and ratio, second dog is 3/2 feet long.

In math, what is a fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

First dog is 5 feet long.

then,

5 feet is equal to 4/5 of the second dog's length.

multiply both sides by 5/4.

5/4 x 5 feet is the second dog's length.

The second dog is 25/4 feet long.

The second dog is 6(1/4) feet long.

Three vertices of parallelogram ABCD are A(-3,1), B(5, 7) and C(6, 2). Find the coordinates of vertex D

Answers

The coordinates of vertex D in the parallelogram ABCD are (7,-3).

What is the relation of vertex in a parallelogram?

In a parallelogram, opposite sides are parallel and congruent. Therefore, the vector that goes from vertex A to vertex B is the same as the vector that goes from vertex C to vertex D, and the vector that goes from vertex B to vertex C is the same as the vector that goes from vertex D to vertex A.

The vector from vertex A to vertex B is [tex]< 5-(-3), 7-1 > = < 8,6 >[/tex]

So, the vector from vertex C to vertex D is also [tex]< 8,6 >[/tex]

The vector from vertex B to vertex C is [tex]< 6-5, 2-7 > = < 1,-5 >[/tex]

So, the vector from vertex D to vertex A is also [tex]< 1,-5 >[/tex]

To find the coordinates of vertex D, we can add the vector from vertex C to vertex D to the coordinates of vertex C.

The coordinates of vertex C are (6, 2)

So, the coordinates of vertex D are [tex](6+1, 2-5) = (7, -3)[/tex]

Therefore, the coordinates of vertex D in the parallelogram ABCD are (7,-3).

What are parallel lines ?

parallel lines can be stated as , they both are equi distant from each other and which never intersect.

From the given figure,

y+12 = 3x + 50

as both are parallel to each other.

y-3x = 38

and 5x  = y + 12

as vertically opposites are always equal .

y = 3x + 38

y = 5x - 12

hence,

5x - 12 = 3x +38

2x = 50

x = 25

put x = 25 in y = 3x + 38

y = 3 * 25 + 38

y = 113

hence the values of x and y are 25 and 113 respectively.

Answers

Answer:

5. x = 25.6

6. x = 11.0

7. x = 41.8°

8. x = 64.2°

9. x = 12.8°

10. x = 51.3°

Step-by-step explanation:

Let's find the x value for each triangle.

For point 5      

We have:

x: is the opposite cathetus to 52°  

20: is the adjacent cathetus to 52°  

52°: is the angle

We can find "x" with the following trigonometric function:

[tex] tan(52) = \frac{x}{20} [/tex]

[tex] x = tan(52)*20 = 25.6 [/tex]

For point 6      

We have:

x: is the hypotenuse  

5: is the opposite cathetus to the given angle  

27°: is the angle

To find "x" we need to use the trigonometric function:

[tex] sin(27) = \frac{5}{x} [/tex]

[tex]x = \frac{5}{sin(27)} = 11.0[/tex]

For point 7

We know:

x°: is the angle

6: is the hypotenuse

4: is the opposite cathetus to x°

Hence, x is:

[tex] sin(x) = \frac{4}{6} [/tex]

[tex] x = sin^{-1}(\frac{4}{6}) = 41.8 [/tex]

For point 8    

We have:

x°: is the angle

14: is the adjacent cathetus to x°

29: is the opposite cathetus to x°

To calculate "x" we need to use the trigonometric function tan(x):

[tex] tan(x) = \frac{29}{14} [/tex]

[tex] x = tan^{-1}(\frac{29}{14}) = 64.2 [/tex]

For point 9    

We have:

x°: is the angle

54: is the hypotenuse

12: is the opposite cathetus to x°

We can use sin(x) to solve for x:

[tex] sin(x) = \frac{12}{54} [/tex]

[tex] x = sin^{-1}(\frac{12}{54}) = 12.8 [/tex]

For point 10  

We have:

x°: is the angle

40: is the hypotenuse

25: is the adjacent cathetus to x°

We need to use cos(x) to solve for x:

[tex] cos(x) = \frac{25}{40} [/tex]  

[tex] x = cos^{-1}(\frac{25}{40}) = 51.3 [/tex]

I hope it helps you!

To solve the given questions, either of the trigonometric functions; sine, cosine and tangent of an angle has to be applied appropriately to either of the questions. The answers to the questions are:

5. x = 25.60

6. x = 11.00

7. x = [tex]41.8^{o}[/tex]

8. x = [tex]64.2^{o}[/tex]

9. x = [tex]12.8^{o}[/tex]

10. x = [tex]51.3^{o}[/tex]

The questions given are right angled triangles which requires the application of trigonometric functions appropriately. A right angle triangle is one that has one of its angles to be [tex]90^{o}[/tex].

So, each of the questions can be solved as follows:

5. Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

Tan 52 = [tex]\frac{x}{20}[/tex]

⇒  x = Tan 52 * 20

       = 25.5988

x = 25.60

6. Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Sin 27 = [tex]\frac{5}{x}[/tex]

⇒ x = [tex]\frac{5}{Sin 27}[/tex]

       = 11.0134

x = 11.00

7. Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Sin x = [tex]\frac{4}{6}[/tex]

        = 0.66667

x = [tex]Sin^{-1}[/tex] 0.66667

  = [tex]41.8^{o}[/tex]

x = [tex]41.8^{o}[/tex]

8. Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

Tan x = [tex]\frac{29}{14}[/tex]

          = 2.0714

x = [tex]Tan^{-1}[/tex] 2.0714

  = [tex]64.2^{o}[/tex]

x = [tex]64.2^{o}[/tex]

9. Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Sin x = [tex]\frac{12}{54}[/tex]

        = 0.22222

x = [tex]Sin^{-1}[/tex] 0.22222

  = [tex]12.8^{o}[/tex]

x = [tex]12.8^{o}[/tex]

10. Cos θ = [tex]\frac{adjacent}{hypotenuse}[/tex]

Cos x = [tex]\frac{25}{40}[/tex]

         = 0.625

x = [tex]Cos^{-1}[/tex] 0.625

  = [tex]51.3^{o}[/tex]

x = [tex]51.3^{o}[/tex]

The solution of the given function cosx - √(3 - 3cos³x) = 0 is C. 30° + 360° n, 330° + 360°n

What are trigonometric identities?

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

We are given the function as;

cosx - √(3 - 3cos³x) = 0

cosx = √(3 - 3cos³x)

Taking square root on both sides.

cos ²x = √(3 - 3cos³x) ²

cos ²x = (3 - 3cos³x)

For solving for x in

cos ²x = (3 - 3cos³x)

cos ²x = 3 (1 - cos³x)

OrScruffy Pals Pet Boxes sends pet supplies in the mail each month. Irma prepaid a 4-month subscription for her cats. She used a one-time coupon and received $8 off the total cost. Irma paid $64 in all. Which equation can you use to find m, the regular cost per month?

Answers

We employ the following equation to get the normal monthly cost:

4m - 8 = 64

Regular monthly expenses amount to $18.

Irma paid for her cats' subscription in advance for a 4-month period.

She saved $8 overall when she utilized a one-time discount.

Irma totaled $64 in payment.

We must identify the equation that can be utilized to calculate m, the average monthly cost.

Let's use m to symbolize the normal monthly expenditure. She signed up for a subscription that would last for four months, thus the full price without the voucher is 4m.

When the coupon is used, the final price is (4m - $8), since she was given a $8 discount.

Irma paid a total of $64 according to the problem, thus we can create the following equation:

4m - $8 = $64

We must now solve for m in order to determine it. Isolating 4m on one side of the equation will be our first step.

4m = $64 + $8

4m = $72

Finally, divide both sides by 4 to solve for m:

m = $72 / 4

m = $18

So, the regular cost per month, m, is $18.

This can be used on right triangles. Now your a and b represent the legs of a triangle and the c represents the hypotenuse(the longest side). If you had a leg that was 2 inches and a second leg that was 4 inches you would plug it into the equation so...

2^2+4^2=c^2

Now evaluate

Now take the square root of 20 which is approximately 4.47 or leave it as square root of 20

If you had one leg and a hypotenuse then plug in and solve like any other equation.

There are lots of different kinds of "tall."Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story.Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story.With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed. When it comes to memory, however, we may want to start carrying video cameras if we want to record the true picture.Which of the following best explains why memories from childhood are unreliable?
