Answer:
57.9°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between trig functions and sides of a right triangle. Here, you're given the side adjacent to the angle of interest, and the hypotenuse of the triangle. This suggests the CAH relationship is the one of interest:
Cos = Adjacent/Hypotenuse
cos(angle) = (741 ft)/(1393 ft)
angle = arccos(741/1393) ≈ 57.863° . . . . . use the inverse cosine function
angle ≈ 57.9°
The wire makes an angle of approximately 57.9° with the ground.
