Question

a vertical tower of height 120 m stands on the ground the angle of elevation of the top of the tower as observed from a point on the ground is 30degree. find the distance of the point from the foot of the tower
​

Answer 1

Step-by-step explanation:

Refer attachment for figure.

A vertical tower of height 120 m stands on the ground the angle of elevation of the top of the tower as observed from a point on the ground is 30°.

MN = 120 m

Assume that the distance of the point from the foot of the tower is x m.

tan30° = MN/NO

Substitute the values,

→ 1/√3 = 120/x

→ x = 120√3

Hence, the distance of the point from the foot of the tower is 120√3.
