Answer:

  • Equation: 2x + x + 72 = 180
  • m∠1 = 72°
  • m∠2 = 108°

Step-by-step explanation:

The angles lie on a straight line summing to total 180 degrees.

Form an equation:

m∠1 + m∠2 = 180

2x + x + 72 = 180

and solve:

3x + 72 = 180

3x = 180 - 72

3x = 108

x = 36

  • Find m∠1: 2(x) = 2(36) = 72°
  • Find m∠2: x + 72 = 36 + 72 = 108°
