Solution:

Note that:

  • Quadrilateral angle measure: 360°
  • (3x - 6) + 2x + 108 + 88 = 360

Simplify the equation to find the measure of x.

  • (3x - 6) + 2x + 108 + 88 = 360
  • => (3x - 6) + 2x + 196 = 360
  • => 3x - 6 + 2x + 196 = 360
  • => 5x + 190 = 360
  • => 5x = 360 - 190
  • => 5x = 170
  • => x = 170/5 = 34

The value of x is 34.
