Given that the triangles are similar.
When triangles are similar, all three pairs of corresponding sides are in the same ratio.
Similarly in the given triangles, the ratio of the corresponding sides are equal.
Cross multiplying, we get
Dividing both sides of the equation by -4.
So, we get
x = 7.
Is that the right equation?

cone:
volume V = ⅓πr²h
= ⅓π17²·20
= 6052.8 yd³
