Answer:
x = 15
Step-by-step explanation:
(2x + 20) + 130 = 180
2x + 150 = 180
- 150 - 150
2x = 30
/2 /2
x = 15
Answer:
x = 15
Step-by-step explanation:
Supplementary = 180 °
Add the numbers
Subtract 150 from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify/Solution =
Hence, x = 15.
