Answer:

77.23°

Explanation:

Given that,

A 135.8 foot wire is attached to the top of the tower.

The wire is attached to the ground 30 feet from the bottom of the tower.

It means,

If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :


\cos\theta=(B)/(H)\\\\\cos\theta=(30)/(135.8)\\\\\theta=77.23^(\circ)

So, the angle the wire make with the ground is equal to 77.23°.
