360/20 is equal to 18 sides
Answer:
Step-by-step explanation:
Basically we want to find x and then plug that in for angle B. How do we find x? Well, we know the angles are complimentary, which means theya dd to 90, so let's start with that.
A + B = 90
8x - 28 + 8x + 22 = 90
16x -6 = 90
16x = 96
x = 6
So there we go. Now to find B
B
8x+22
8(6)+22
48 + 22
70
Answer: |X-2|+3
I graphed it on the a calculator :)
If the height Ration is a/b, then
The ration of the arias S₁ & S₂==> S₁/S₂ = a²/b² and
The ration of the volumes V₁ & V₂==> V₁/V₂ =a₃/b₃
V₁ =135 cm³ the ration of the heights = 3/2, Calculate V₂
V₁/V₂ =3³/2³ = 27/8===> 135/V₂ = 27/8==> V₂=(135x8)/27 = 40cm³
