Answer:
38.2°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relation:
Tan = Opposite/Adjacent
In this context, it means ...
tan(A) = CB/AB
tan(x°) = 48/61
The inverse tangent function is used to find the angle when you know its tangent.
x° = arctan(48/61) ≈ 38.2°

Additional comment
On many scientific and graphing calculators, the inverse tangent function is the 2nd function of the tan key. It may be labeled tan⁻¹. Usually, the calculator will have a mode setting that allows you to select the units used for presentation of the angle. You many have to choose degrees if the calculator is giving you a number less than 1.
