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°
