Question

The angles of depression of the top and bottom of a tower as seen from the top of a 60√3m high cliff 45 ° and 60°respectively . Find the height of the tower .

Answer 1

60 root3/ base = tan60

base = 60root3 / root3

b = 60 m

tan 45 = h / 60

h = 60m

height of buillding = 60root3 - 60

= 60(root3 -1)

= 43.92m
