Home » Aptitude » Trigonometry » Question

If a 48 m tall building has a shadow of 48 √3 m., then the angle of elevation of the sun is

1. 15°
2. 60°
3. 45°
4. 30°

Correct Option: D

AB = Building = 48 metre
BC = Shadow = 48√3 metre
∠ACB = θ = ?
AB BC

∴ tan θ =	AB	=	48
	BC		48√3

⇒ tanθ =	1	= tan 30°
	√3

θ = 30°
