two buildings stand 90 feet apart at their closest points. at those points the angle od depression from the top of the taller building to the top of the shorter building is 12 degrees. how much taller is the taller building
Angle of depression = Angle of elevation = 12° We will use trigonometry: tan 12° = h / 90 h = 90 · tan 12° h = 90 · 0.212556 h = 19.13 ft Answer: The taller building is 19.13 ft taller.
