Q. 45.0( 3 Votes )

From a point on the ground, 20 m away from the foot of a vertical tower, the angle of elevation of the top of the tower is 60°, what is the height of the tower?

Answer :

Let the height of the tower be AC = x m

Distance from the foot of the vertical tower = 20m

tan 60° = AC/ BC

√3 = x / 20 ( tan 60° = √3)

x = 20√3
