A surveyor sees a building across the river. Standing at point A he measures the angle of elevation
from the ground to the top of the building to be 30 degrees. He steps back 100 feet and again
measures the angle of elevation and finds it to be 15. (See Figure 12.26.) Assuming that it makes a
90-degree angle with the floor, approximately how tall is the building?
