The shadow of a pole $5\sqrt3\text{ m}$ high is $5\text{ m}$ long. Find the angle of elevation of the sun.

Worked solution (try it first)

The pole is opposite the angle of elevation and the shadow is adjacent, so $\tan\theta = \frac{5\sqrt3}{5} = \sqrt3$ .
$\tan60^\circ = \sqrt3$ , so $\theta = 60^\circ$ , option C.
