Question

From a point on the ground 60m away from the foot of a tower, the angle of elevation of the top of the tower is 30°. The angle of elevation of the top of a water tank (on the top of the tower) is 45°. Find the (i) height of the tower.
(ii) depth of the tank.

Answer 1

Answer:

tan 30 = x/60

1/root3 = x/60

x=60/root3

x=20root3 m

therefore depth of the tank = 20root3 m
