Answer:

50 degrees

Step-by-step explanation:

Since this is an isosceles triangle, and the measurements on the left and right are the same, that means that both angle measurements on the bottom are the same.

180 - 80 = 100

100/2 = 50

Answer:

The slope of a line parallel to this line will be: -7/9

The slope of the perpendicular line will be:

[tex]\frac{-1}{\frac{-7}{9}}=\frac{9}{7}[/tex]

Step-by-step explanation:

We know the slope-intercept form

[tex]y=mx+b[/tex]

Here,

Given the equation

[tex]7x+9y=5[/tex]

simplifying to write in the lope-intercept form

[tex]y=-\frac{7}{9}x+\frac{5}{9}[/tex]

Thus, the slope of the line is: -7/9

The slope of a line parallel to the line:

We have already determined that the slope of the line is: -7/9

Thus, the slope of a line parallel to this line will be: -7/9

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: -7/9

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus,  the slope of the perpendicular line will be:

[tex]\frac{-1}{\frac{-7}{9}}=\frac{9}{7}[/tex]

Answer:

x=√3

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2+3x−2=3x+7

Step 1: Subtract 3x from both sides.

3x2+3x−2−3x=3x+7−3x

3x2−2=7

Step 2: Add 2 to both sides.

3x2−2+2=7+2

3x2=9

Step 3: Divide both sides by 3.

Answer:

D on edge

Step-by-step explanation:

The value of x will be 12°

It should be noted that vertically opposite angles are equal.

Therefore, 4x will be equal to 48°

The value of x will be calculated thus:

4x = 48

Divide

x = 48/5

x = 12

Therefore, the value of x will be 12°

Answer: 12

Step-by-step explanation:

vetrtical angles are equal to eachother. So to solve you would do

4x=48

then you have to get x by itself and to do so you need to divide the four by itself which will leave one. And as a rule you have to do it to the other side as well so…

4/4x=48/4

x=12

And that’s your answer

Answer:

m∠1 = 60°

m∠2 = m∠4 = 39°

m∠3 = m∠5 = 21°

Step-by-step explanation:

ΔWXY is a equilateral angle,

Therefore, all angles of the the triangle are equal in measure.

m∠W + m∠X + m∠Y = 180°

3m∠W = 180°

m∠W = 60°

Since, ΔWZY is an isosceles triangle,

m∠3 = m∠5

m∠3 + m∠Z + m∠5 = 180°

m∠3 + 138° + m∠3 = 180°

2m∠3 = 180 - 138

m∠3 = 21°

Therefore, m∠3 = m∠5 = 21°

Since, m∠2 + m∠3 = 60°

m∠2 = 60 - 21

        = 39°

Since, m∠4 + m∠5 = 60°

m∠4 = 60 - 21

        = 39°

m∠1 = 60°

Formulas (for easier reference):

Volume of cone: [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]

Volume of hemisphere: [tex]\frac{2}{3}[/tex][tex]\pi[/tex]r³

Surface area of cone without base: [tex]\pi[/tex]rl

Surface area of hemisphere without base: 2[tex]\pi[/tex]r²

We can just apply the formulas for the question:

Volume of toy = ([tex]\pi[/tex] × 6² × [tex]\frac{8}{3}[/tex]) + ([tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] 6³)

                        = 96[tex]\pi[/tex] + 144[tex]\pi[/tex]

                        = 240[tex]\pi[/tex]

                        = 754cm³ (3 s.f.)

Surface area of toy = ([tex]\pi[/tex] × 6 × 10) + (2 × [tex]\pi[/tex] × 6²)

                                = 60[tex]\pi[/tex] + 72[tex]\pi[/tex]

Given:

Principal = Rs. 2000

Rate of interest = 20% p.a. compounded quarterly.

Time = 1 year

To find:

The compound interest.

Solution:

Formula for amount:

[tex]A=P\left (1+\dfrac{r}{n}\right)^{nt}[/tex]

where,

P = Principal

r = Rate of interest

t= Time

n = number of times interest compounded in an year.

Putting P=2000, r=0.2, n=4 and t=1, we get

[tex]A=2000\left (1+\dfrac{0.2}{4}\right)^{4(1)}[/tex]

[tex]A=2000\left (1.05\right)^{4}[/tex]

[tex]A=2000\left (1.21550625\right)[/tex]

[tex]A=2431.0125[/tex]

Now, the compound interest is

[tex]C.I.=A-P[/tex]

[tex]C.I.=2431.0125-2000[/tex]

[tex]C.I.=431.0125[/tex]

Therefore, the compound interest is Rs 431.0125.

Step-by-step explanation:

The 13th term of the given arithmetic sequence is estimated as a = 67x - 64.

In Arithmetic Progression, the difference between the two arithmetic orders is a constant value (AP). Arithmetic Sequence is another name for it.

We'd get to a few specific terms in AP, that were denoted as:

The AP may also be defined using common distinctions, as shown below.

Now, for the given question;

Consider the first term is 'a₁' = -5x+8

Consider the second term as 'a₂' =  x+2

Then, the common difference is calculated as;

d = a₂ - a₁

d = x+2 -(-5x+8)

d = x+2 + 5x - 8

d = 6x - 6

Now, find the 13th term using the formula of nth term;

an = a + (n − 1) × d

a₁₃ = a₁ + (13 - 1) × d

Substituting the values;

a₁₃ = -5x + 3 + (13 - 1) × (6x - 6)

a₁₃ = -5x + 3 + (12) × (6x - 6)

a₁₃ = -5x + 3 + 72x - 72

a₁₃ = 67x - 64

Therefore, the value of the 13th term of an  arithmetic sequence is found as a₁₃ = 67x - 64.

The angle of descent is 14.2

The measure of the angle of the descent will be 14.22°.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

A plane is sliding to a runaway. At a height of 15.2 miles, its level distance to the runway is 60 miles.

The tangent of angle θ is the ratio of the height to the base of the right-angle triangle.

The measure of the angle of the descent will be given as,

tan θ = 15.2 / 60

tan θ = 0.2533

θ = tan⁻¹ 0.2533

θ = 14.22°

The measure of the angle of the descent will be 14.22°.
