Answer:

  • Same side exterior angles
  • x = 15

Step-by-step explanation:

The indicated angles are same side exterior angles since located on the same side of the transversal and exterior to parallel lines.

Same side exterior angles are supplementary, so their sum is 180.

Solve the following equation for x

  • 7x + 3 + 4x + 12 = 180
  • 11x + 15 = 180
  • 11x = 165
  • x = 165/11
  • x = 15

Angles are supplementary as they are same side exterior angles

  • 7x+3+4x+12=180
  • 11x+15=180
  • 11x=165
  • x=15
