So, there is a explanation paragraph right before question 93. In summary, it says that the distance a projectile travels is (v^2/32)* sin(2*x) where v is the velocity but x is the angle of elevation. So we can do 200=75^2/32 * sin(2x). After some minor manipulations we get 256/225=sin(2x). Then you can solve it from there.
