Answer:
Step-by-step explanation:
search up 90 cents in the form of x for b.
x = 18 degrees
because lines n and m are parallel, 3x and 126 are same side interior angles. This means that when added up they equal 180, so make an equation as so:
3x + 126 = 180
Solve for it and x will equal 18.

3^0
Apply rule a^0=1 a=0
=1
