1. The problem statement, all variables and given/known data http://postimage.org/] [/PLAIN] [Broken] free picture upload 2. The attempt at a solution I want to go width times delta height. To do this I must describe width in terms of height. Here they used the Pythagorean theorem which is weird to me because I don't see a nice triangle. Where h meets w the triangle extends outside of the circle. We divide w by 2 I guess to treat it as like a radius? I guess my question is how do I describe width in terms of height in this context?
