Answer:
22 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the necessary relationship. If the sledding slope is modeled as the hypotenuse of a right triangle with 25° as one of the acute angles, the side opposite the angle (the hill height) satisfies ...
Sin = Opposite/Hypotenuse
Opposite = Hypotenuse × Sin
height = (52 ft)sin(25°) ≈ 22.0 ft
The height of the hill is about 22 feet.
