Answer:

  • 102 and 102

Explanation:

There is no diagram attached

It is assumed the angles are vertical

Vertical angles are congruent as per vertical angles theorem

  • 3x + 21 = 6x - 60
  • 6x - 3x = 21 + 60
  • 3x = 81
  • x = 81/3
  • x = 27

Angle measures

  • 3*27 + 21 =81 + 21 = 102

So the answer is

  • 102 and 102
