To estimate the height of a building, two students find the angle of elevation from a point (at ground level) down the street from the building to the top of the building is 31∘ . From a point that is 400 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 53∘ . If we assume that the street is level, use this information to estimate the height of the building. What is the height of the building in feet?
