The angle of elevation of the sun when the length of the

The angle of elevation of the sun when the length of the shadow of a pole is √3 times the height of the pole will be :

Let us draw the figure from the given question.
Given, AC = √3 AB ......... ( 1 )
and ∠BCA = θ .
In triangle ACB , we have

∴	cot θ =	AC	= √3	⇒	tan θ =	1	[ From equation ( 1 ) ]
		AB				√3

⇒ tan θ = tan 30° ⇒

30°.
