Question

Length of shadow of a tree 12m high when Sun's elevation is ${45}^{\circ }$ is $12\sqrt{3}$

• A. True
• B. False

Answer 1

The correct option is B

False

$\Rightarrow tan\theta$ = $\frac{AB}{BC}$
$\Rightarrow tan\theta$ = $\frac{12}{12\sqrt{3}}$

The angle of elevation is ${30}^{\circ }$ and not ${45}^{\circ }$
