Question

A. 22.59
B. 14.34
C. 20.48
D. 10.70

Answer 1

B. 14.34

Explanation:

The mnemonic SOH CAH TOA reminds you of the relationship between the side opposite the angle of interest and the hypotenuse:

Sin = Opposite/Hypotenuse

For the given triangle, this means ...

sin(35°) = b/25

b = 25·sin(35°)

b ≈ 14.34
