Asked by Jenna

From the roof of a building, the angle of elevation of the top of a taller building is 37 degrees. The angle of depression of the base of the building is 28 degrees. The buildings are 21 m a part. Determine the height of the taller building
Answered by Damon
tan 37 = htop/21
tan 28 = hlow /21

so
htop + hlow = 21(tan37+tan28)
