**Answer:**

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

To window: tan 28.5=height-to-window/50 ->

50 tan 28.5=height-to-window ->

27.487ft

Height of building: 50 tan 35 = 35.010 ft
