Question

A flagstaff 6 metres high throws a shadow 2$\sqrt{3}$ m long on the ground. The angle of elevation (in degree) of the top of the flagstaff from the point where the shadow ends.

___

Answer 1

Given AB = 2$\sqrt{3}$m

And BC = 6m

$\tan$ A = $\frac{BC}{AB}$ = $\sqrt{3}$

$⟹$ A = ${60}^{\circ }$
