A man is standing on level ground 50 feet away from the wall of a building.
He looks up at a window on the building. The angle of elevation to the bottom
of the window is 28.5°. He then looks up at the top of the building. The angle of
elevation to the top of the building is 35°. What is the approximate distance
between the bottom of the window and the top of the building?

50 (tan 35 - tan 28.5) = 7.86 ft
