Two poles of different heights are standing on a plane ground separated by some distance. The angle of depression from the top of the taller pole to the bottom of the smaller pole is α and the angle of depression from the top of the smaller pole to the bottom of the taller pole is β. If the height of smaller pole is “h” then show that the square of height of the taller pole is given as [h2 (sec2α – 1)] / [(secβ + 1)(secβ - 1)].

Answer:
The distance between two vertical poles is 60m. The height of one of the pole is double the height of the other. The angles of elevation of the top of the poles from the middle point of the line segment joining their feet are complementary to each other. Find the heights to the poles.
