Question

A tower, 28.4ft high must be secured with a guy wire anchored 5ft. from the base of the

tower. What angle will the guy wire make with the ground?

Answer 1

let$\theta$ be the angle between the wire and the ground.

$tan\theta =opp/adj$

$tan\theta$ =28.4/5

$tan\theta=5.68$

$tan^-1 (tan\theta)=tan^-1(5.68)$

$\theta$ =80.02
