Q) The length of the shadow of a tower on the plane ground is √3 times the height of the tower. Find the angle of elevation of the sun.

Ans:

Let the tower be AB and its shadow be AC and angle of elevation from point C be θ

Given that AC = √3 x AB

Now in Δ ABC, tan θ = 

It means,  θ = 30⁰

Therefore, angle of elevation of the sun is 30⁰
