Answer:
E. 54.462
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship involving the adjacent side and the hypotenuse:
Cos = Adjacent/Hypotenuse
cos(C) = CB/CA = 5/√74
Then the angle is found using the inverse function:
C = arccos(5/√74) ≈ arccos(0.581238)
C ≈ 54.462°
The measure in degrees of angle C is about 54.462.
