Question : If the height of a pole is $2\sqrt{3}$ metres and the length of its shadow is 2 metres, then the angle of elevation of the sun is:
Option 1: 90°
Option 2: 45°
Option 3: 30°
Option 4: 60“
Correct Answer: 60“
Solution : Let AB be the pole and AC be the shadow of the pole. Let $\angle$ ACB = $\theta$ Then, AB = $2\sqrt{3}$ m and AC = 2 m $\tan\theta=\frac{2\sqrt{3}}{2}$ ⇒ $\tan\theta=\sqrt{3}$ ⇒ $\tan\theta=\tan60°$ ⇒ $\theta=60°$ Hence, the correct answer is 60°.
