Answer:

opposite side: 120.24 cm

hypotenuse: 121.02 cm

Step-by-step explanation:

The mnemoic SOH CAH TOA is useful here. It tells you ...

... Tan = Opposite/Adjacent

so

... Opposite = Adjacent×Tan = (13.7 cm)×tan(83.5°) ≈ 120.24 cm

It also tells you ...

... Cos = Adjacent/Hypotenuse

so

... Hypotenuse = Adjacent/Cos = (13.7 cm)/cos(83.5°) ≈ 121.02 cm
