Answer:7.7 ft

Step-by-step explanation:The mnemonic SOH CAH TOA reminds you of the relation …

Sin = Opposite/Hypotenuse

You are given the angle and the hypotenuse, and want to know the length of the side opposite. Filling in the problem values, you have …

sin(D) = CE/CD

sin(57°) = CE/(9.2 ft)

(9.2 ft)sin(57°) =

CE ≈ 7.7 ft
