A hot air balloon hovers 75 feet above the ground. The balloon is tethered to the ground
with a rope that is 125 feet long. At what angle of elevation, E, is the rope attached to the ground?
Round your answer to the nearest degree.

Angle of elevation is 37°

Step-by-step explanation:

As we have the opposite side 75 ft to the angle and the hypotenuse 125 ft, we can find the sine value as,

sin θ = opp/ hyp

       = 75/125

     = 0.6

θ = sin⁻¹ (0.6) = 36.9°≈ 37°

So angle of elevation is 37°.
