The height of a t
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°.
