Answer 1

Answer:

  x ≈ 10.6

Step-by-step explanation:

The hypotenuse and the side adjacent to the angle are the ones marked on the diagram. The relation with the angle is ...

  Cos = Adjacent/Hypotenuse

  cos(28°) = x/12 . . . . . . . . . use the given values

  x = 12·cos(28°) ≈ 10.6 . . . multiply by 12
