Question

A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to

be attached 6 feet from the top and is to make an angle of 23° with the ground?
Give your answer to the nearest tenth of a foot.

Answer 1

522.1

Explanation:

Calculated based on 2 given angles and 1 given side.

Side b = 204

Angle ∠A = 90°

Angle ∠B = 23°

Angle ∠C = 180-90-23 = 67°

a = b·sin(A)/sin(B) = 522.09815
