# The height of a t

Answer :

We have to measure the angle of elevation of the source of light from the end of the bamboo tree with the horizontal line as the reference.

i,e; We have to find ∠ LCM

But from the diagram it is clear that, ∠LCM = ∠ACB

Now, using trigonometric ratios,

Θ = 30°

Therefore, the angle of elevation of the source of light is 30°.
