Answer:
Thale's theorem stated that if a line parallel to the base of the triangle intersects it, the ratio of sides of the respective sides is equal
In this diagram, since the 2 horizontal lines are parallel
the ratio of the 2 sides on the left and the 2 sides on the right will be equal
Hence,
x/15 = 2/10
x = 30/10
x = 3
I think
sqrt 7x^2 - 7*sqrt 49x
x sqrt7 - 7 (7) sqrtx
x sqrt7 - 49 sqrtx
V = (1/3)pi*r^2*h that's the formula to used to get the volume of the cone
