Answer:
Step-by-step explanation:
The two angles labelled and are co-interior angles. When two parallel lines are cut by a traversal, co-interior angles are supplementary, meaning they add up to 180 degrees. Therefore, if line L is parallel to line M, and must be supplementary:
Combine like terms:
Subtract 10 from both sides:
Divide both sides by 10:
6x+8+4x+2=180
so!! 10x+10=180
10x=170
x=17
Answer: 3
