A-1538=1074
a=1538+1074
a=2612
b+718=1074
b=1074-718
b=356
2000-c=1074
c=2000-1074
c=926
2612-356+926=3182
Best guess is it’s the second one but I believe it’s between A and B sorry If I’m wrong.
Infinitely many because if you take the top equation and multiply it by 2 you get the same equation. That means that any number you plug in for x is a solution
So the transversal (line that crosses lines a and b) is 180 since its a straight line. given the angle degree 125, you can do 180-125 to get angle m.
