A boy standing 70m away from a flag-post, observes that the angle of elevation from the top and bottom of a tower on top of the flag-post are 57degrees and 69degrees respectively.
:
Use the tangent of two right triangle to find the height of the pole and the height of the pole + the tower
tan(57) =
P = 70 * 1.540
P = 107.8 meters
and
tan(69) =
T+107.8 = 70 * 2.605
T + 107.8 = 182.356
T = 182.356 - 107.8
T = 74.556 ft if the height of the tower
