Question

How can I solve this problem?

Answer 1

Answer:

  116

Step-by-step explanation:

The sum of angles in a quadrilateral is 360°. The figure here is symmetrical about the line NQ, so ∠P = ∠M = x°. Using these facts, we can write ...

  ∠M +∠N +∠P +∠Q = 360°

  x° +28° +x° +100° = 360° . . . . fill in the angle values

  2x = 232 . . . . . . . . . . . . . . . . . divide by °, subtract 128

  x = 116 . . . . divide by 2
