Answer:

lower Right.

Step-by-step explanation:

Remark

The two angles share the same side of vertically opposite angles. That makes them supplementary which means the two angles add to 180 degrees.

Equation

4x + 8x + 12 = 180         Combine like terms on the left

Solution

  • 12x + 12 = 180                Subtract 12 from both sides
  • 12x = 180 - 12                 Combine
  • 12x = 168                        Divide by 12
  • x = 168/12
  • x = 14
