Answer:

     x ≈ 67.1

Step-by-step explanation:

The side adjacent to x° is given, along with the hypotenuse. That suggests the relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

  cos(x°) = 28/72 = 7/18

The angle is found from the cosine using the inverse cosine function:

  x° = arccos(7/18)

  x° ≈ 67.1°
