(Q8) A tower stands vertically on the ground. From a point which is 15 meter away from the foot of the tower, the angle of elevation of the top of the tower is 45o. What is the height of the tower?

45o15 mhtower

Solution :

Let the height of the tower = h m

Distance of the point of observation from the foot of the tower =15 cm.

Angle of elevation of the top of the tower = 45o

From the figure tanθ =
opp. side
adj. side

tan ° =
h
=
h

∴ h = × = m
