Question

A person is standing exactly 36 ft from a telephone pole. there is a 30° angle of elevation from the ground to the top of the pole. what is the height of the pole? 12 ft ft 18 ft ft

Answer 1

Let in a right angled triangle ABC,

AC be the height of telephone pole,

/_ B = 30

and BC= 36 ft

to find height of the pole.

We Know that Tan B = Perpendicular/Base

= AC/BC

tan 30 = AC/36

0.577 = AC/36

AC = 20.722

So the height of the telephone = 20.722
