Question

The angle of elevation of the rop of a tower,from a piont on the ground and at a distance of 30m from its foot is 30*.Find the height of the tower

Answer 1

Given, angle of elevation = 30°
Distance of the point of observation from the foot of the tower = 30m
Let the height of the tower be "h" metres.
So, tan 30° = h/30 = 1/√3
⇒ h = 10√3 m = 17.32 m
Hence the height of the tower is 10√3 metres or 17.32 metres.
