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 38°. From a point that is 250 feet closer to the building, the angle of elevation (at ground level) to the top of the building is 49°. If we assume that the street is level, use this information to estimate the height of the building. The height of the building is feet.

Question
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 38°. From a point that is 250 feet closer to the
building, the angle of elevation (at ground level) to the top of the building is 49°. If we assume that the
street is level, use this information to estimate the height of the building.
The height of the building is
