Solution (1):

Note that:

  • Sum of interior angles = 180°

This means that...

  • 5x + 3x + 2 + 130 = 180

Finding the value of x.

  • 5x + 3x + 2 + 130 = 180
  • => 8x + 132 = 180
  • => 8x = 180 - 132
  • => 8x = 48
  • => x = 6

Solution (2):

Note that:

  • Sum of interior angles = 180°

This means that...

  • x + 66 + x + 86 + 50 = 180°

Finding the value of x.

  • x + 66 + x + 86 + 50 = 180°
  • => 2x + 202 = 180°
  • => 2x = -22
  • => x = -11
