Answer:
x = 18 degrees
Step-by-step explanation:
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.

38.25/45= .85
TO CHECK
.85 times 45 equals 38.25
Y=mx+b
m=slope
b=yintercept
given
slope=-1/4
