1. The problem statement, all variables and given/known data I've attached a diagram of the problem. 2. Relevant equations Trig functions (soh cah toa) and pythagorus theorem a^2 + b^2 = c^2 3. The attempt at a solution I've tried a bunch of things but I can't find a start. I know I can't assume that triangle ABC is a right triangle. I tried breaking it up into little triangles, but can't seem to find a good starting point.
