Question

Find the angle of elevation of the Sun when the shadow of a pole $h$ $m$ high is $\sqrt{3}h$ $m$ long.

Answer 1

$\tan \theta =\frac{P}{B}$ $\therefore$ Perpendicular $=$P, Base$=$B

$=\frac{4}{\sqrt{3}4}$

$\tan \theta =\frac{1}{\sqrt{3}}$

$\tan 30=\frac{1}{\sqrt{3}}$

$\theta ={30}^o$.
