A flagpole 94.9 ft tall is on the top of a building. From a point on level ground, the angle of elevation of the top of the flagpole is 34.2°, while the angle of elevation of the bottom of the flagpole is 25.1°. Find the height of the building. The building is about nothing ft tall. (Round to the nearest foot as needed.)
