Answer 2

Given:

Height of a pole = 10m

The altitude of the sun is 30°

To Find,

The length of the shadow.

Solution,

The sun's altitude is 30°,

⇒ tan30° = $\frac{opposite side}{adjacent side} = \frac{length of the pole}{length of the shadow}$

⇒$\frac{1}{\sqrt{3} } =\frac{10}{length of the shadow}$

⇒Length of the shadow = $10\sqrt{3}m$.

Henceforth, the length of the shadow when the sun's altitude is 30° = $10\sqrt{3}m$.
