Answer:
- Equation: 2x + x + 72 = 180
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°
