Trigonometry

Easy

The angle of elevation from a point situated at a distance of 70 meter from the base of a tower is $60^0$ . The height of the tower is:

$35\sqrt{3}$ meter

$45\sqrt{3}$ meter

$70\sqrt{3}$ meter

$90\sqrt{3}$ meter

✅ Correct Option: 3

In the right triangle formed by the tower and the ground, $\tan 60° = \dfrac{h}{70}$ .

Since $\tan 60° = \sqrt{3}$ , we get $h = 70\sqrt{3}$ metres.
