Home » Aptitude » Trigonometry » Question

The length of shadow of a tower is √3 times that of its length. The angle of elevation of the sun is :

1. 45°
2. 30°
3. 60°
4. None

Correct Option: B

Let the height of tower be x units.
∴ Length of shadow = √3x units In ∆ABC,

∴ tanθ =	AB	=	x	=	1
	BC		√3 x		√3

⇒ tanθ = tan30°
⇒ θ = 30°
