Two buildings are 30m apart. The angle of depression from the top of the taller building to the top of the shorter building is 12 degrees. The height of of the shorter building is 45 m. What is the height of the taller building?

Answer 1

draw the diagram. It should be clear that
(h-45)/30 = tan12°
Now solve for h

Answer 2

Two office buildings are 51 meters apart. The height of the taller building is 207 meters. The angle of depression from the top of the taller building to the top of the shorter building is 15°. Find the height of the shorter building to the nearest meter.
