If the height of a pole is 2√3 metres and the length of its shadow is 2 metres, find the angle of elevation of the sun ?

A. 70°
B.  80°
C. 60°
D.  50°

Let AB be the pole and AC be its shadow. Let 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°
