Answer:
- x = 109
- x = 31
- x = 140
Step-by-step explanation:
1)
x + 71 = 180
x = 180 - 71
x = 109
2)
x + 149 = 180
x = 180 - 149
x = 31
3)
x + 40 = 180
x = 180 - 40
x = 140
Conclusion:
- If x + 71 = 180 then the value of x is 109.
- If x + 149 = 180 then the value of x is 31.
- If x + 40 = 180 then the value of x is 140.
