Question

Refer to the figure given. What is the length of the shadow that is formed by the stick AB of length 10$\sqrt{3}$ m (in metre)? ___

Answer 1

BC is the shadow.
In ΔABC,
tan${30}^{\circ }$ = $\frac{AB}{BC}$

$\Rightarrow$ $\frac{1}{\sqrt{3}}$ = $\frac{10\sqrt{3}}{BC}$

$\Rightarrow$ BC = 30 m

$\therefore$ The length of the shadow that is formed by the stick AB is 30 m.
