Question

Find the angel of evelation of the sun when the the shadow of a pole $h$ meter high is $\sqrt{3}h$ meters long

Answer 1

$\tan \theta =\frac{P}{B}=\frac{AB}{CB}$

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

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

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

$[\tan {30}^o=\frac{1}{\sqrt{3}}]$

$\theta ={30}^o$.
