Answer:
77.23°
Step-by-step 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 :
[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{30}{135.8}\\\\\theta=77.23^{\circ}[/tex]
So, the angle the wire make with the ground is equal to 77.23°.
