Q42 of 68 Page 9

An idol 30m tall stands on a pillar 15 m high. Find the angle in degrees which the idol subtends at a point distant m from the base of the pillar.


Let AB be the idol and BC be the pillar


So, AB = 30 m


and BC = 15 m


Distance from the base of pillar = 15√3 m


Now, In right ΔACD, we have







⇒ tan x = tan 30°


⇒ x = 30°


Hence, the angle subtends from the base of the pillar is 30°

A ladder is placed against a building, and the angle of elevation of the top of the ladder is 60°. The ladder is turned so that it is placed against another building on the other side of the lane and the angle of elevation, in this case, is 45°. If the ladder is 26 m long, then find the width of the lane.
