Answer 1

9514 1404 393

Answer:

11.9 cm

Explanation:

The mnemonic SOH CAH TOA reminds you of the relation between the side opposite the angle (BC) and the hypotenuse (14 cm).

Sin = Opposite/Hypotenuse

sin(58°) = BC/(14 cm)

BC = (14 cm)×sin(58°) . . . . . multiply by the denominator

BC ≈ 11.9 cm
