Answer:
y = 16
Again, let me know if you don't see how they are supplementary
Step-by-step explanation:
This looked super overwhelming when I first looked at it. Thankfully it's actually pretty simple.
We want p and q to be parallel and want to deal with y. Well both of those are on n as the transversal, so we can pretend m doesn't exist. The two angles labeled are supplementary to each other, if you cannot tell that let me know, but adding the two together make 180.
So you just need to solve 6y+12+4y+8=180
6y+12+4y+8=180
10y + 20 = 180
10y = 160
y = 16
Again, let me know if you don't see how they are supplementary
