plssss helpppp againnnn

Answer:
x = 34°
Step-by-step explanation:
To solve for 'x', we will need to use the Supplementary Angles theorem. This states that on a line, all angles must add up to 180°.
We can set up a simple algebraic equation to solve for 'x':
180 = x + 12 + 100 + x
180 = 112 + 2x **Combine like terms
68 = 2x **Divide both sides by '2'
x = 34°.
Therefore, the measure of ∠x = 34°.
Answer: x= 34
Step-by-step explanation:
x + 12 + 100 +x = 180 use the equation and combine like terms
2x + 112 = 180 subtract 112 from both sides
-112 -112
2x = 68 Divide both sides by 2
x = 34
Check: 34 + 12 +100 + 34 = 180
180 = 180
