Question

If the altitude of the sum is at 60°, then the height of the vertical tower that will cast a shadow of length 30 m is

(a) $10\sqrt{3}$ m

(b) 15 m

(c) $\frac{30}{\sqrt{3}}m$

(d) $15\sqrt{2}m$

Answer 1

Let be the height of vertical tower

Given that: altitude of sun is and shadow of length meters.

Here, we have to find the height of tower.

So we use trigonometric ratios.

In a triangle,

Hence the correct option is .
