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.

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
