19. Bob looks up at the top of a nearby tree that he knows is 200 feet tall and finds that the angle of elevation is 50 degrees. He then walks some distance closer to the base of the tree and looks up again to find the angle of elevation is now 70 degrees. How far did he walk? Your answer should be given in terms of trig functions.
