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.
Pick one.
A) 30° B) 45° C) 60° D) 90° E) None of these
Solution   Let AB be the pole and AC be its shadow.   Then, &lt; ACB	= θ.   Then, AB= 2 √3 m, A60° = 2m,   tanθ= AB/A60°=2√3/2   = √3   θ=60°   Answer 60°
