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 33 degrees. From a point that is 300 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 49 degrees. If we assume that the street is level, use this information to estimate the height of the building.
The height of the building is_____

Steve,
h/tan 49° = h/tan 33°  300
solve for h
