From the top of a 50 m high tower, the angles of depression of the top and bottom of a pole are observed to be 45° and 60° respectively. Find the height of the pole.
In the fig CE is the height of the pole and x be the distance between tower and pole.
tan 45° =
x = 50-h ----- (1)
tan 60° =
x = -----(2)
On substituting value of x in eqn (1), we get
50 – h =
h = 50 - ⇒
Therefore the height of the pole is 21.13m
