**If the height of a pole is 2√3 meters and the length of its shadow is 2 meters, find the angle of elevation of the sun.**

A. 50°

B. 60°

C. 70°

D. 80°

**B. 60°**

Let AB be the pole and AC be its shadow. Let the angle of elevation, ∠ACB = θ. Then, AB = 2√3m, AC = 2 m. tan θ = AB/AC = 2√3/2 = √3 θ = 60°. So, the angle of elevation is 60°
