Answer:

  21

Step-by-step explanation:

The mnemonic SOH CAH TOA helps you remember ...

  Sin = Opposite/Hypotenuse

You choose this relation because the given lengths are the hypotenuse (14) and the side opposite (5) the angle (x°). Then ...

  sin(x°) = 5/14

  x° = arcsin(5/14) ≈ 20.92°

  x ≈ 21
