Question

Robert sees a bird sitting on top of a telephone pole. He estimates the angle of elevation to the top of the pole to be 53°. If he is standing 15 feet from the base of the pole, about how tall is the telephone pole? (Assume the pole meets the ground at a right angle.)

Answer 1

Answer:

height = 20 feet

Step-by-step explanation:

let height of the pole be h feet.

tan53° = height of the pole / horizontal distance

between the pole and Robert

= h / 15

=> h = 15 tan 53°

= 15×(4/3)

= 20 feet

therefore telephone pole is 20 feet long
