Answer:

The largest angle measure in triangle DEF = 82°  

Explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

So, the shape of the triangles ABC and DEF are the same.

Sine the shape is similar the angle of the dilated triangle and considered triangle are the same.

Find X. 2x + 15 = 20
lakkis [162]

Answer:

x = 5/2     or     x = 2.5

Step-by-step explanation:

To solve for x, we will have to get the equation 2x + 15 = 20 into the form x = _. That will be our answer.

2x + 15 = 20

Subtract 15 from both sides to get rid of the +15 on the left side.

2x = 20 - 15

Simplify.

2x = 5

Divide both sides by 2 to get rid of the coefficient of 2 on the left side.\

x = 5/2 = 2.5

x = 5/2   or    x = 2.5

I hope you find my answer helpful. :)

The diameter of a volleyball is 8.15 inches. What is the volume of the ball, rounded to the nearest hundredth?
Nana76 [90]
<span>So we want to know the volume V of the volleyball if we know the diameter d=8.15 inches and we need to round it to the nearest hundreth. The volume of a volleyball is V=(4/3)r^3*pi, and since 2 radius are equal to the diameter we need to get the radius, so 2r=D and r=D/2 or r=4.075 inches. Now we get the volume after inputting the numbers: V=283.303032 inches^3. Rounded to the nearest hundreth: V=283.30</span>
