Answer:
3
Step-by-step explanation:
Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.
b
width = 5cm
hope it helps
If A is parallel to B, then angles 2 and 4 are same side interior and they are supplementary. Thus,
2x + 10 + 4x + 80 = 180 and
6x = 90 so
x = 15
