From the top of a 7-meter-high building, the angle of elevation of the top of a cable tower is 60° and the angle of depression of its foot is 45°. Determine the height of the tower in meters.
+37146 Distance to tower from building tan 45 = d/7 solve for d = 7 m
Distance to top of tower from 7 m up tan 60 = h/7 h = 12.12 m
add h + the 7 m = height = 19.12 m
