Find the value of x to make A||B
2 answers:
X=90 you have to make the two equations equal
Answer:
x=90
Step-by-step explanation:
If the two liners were parallel, <1 and <4 would be congruent because they are corresponding angles. Since they are congruent, we can set them equal to each other
<1=<4
3x-160=x+20
Solve for x, by getting x by itself
Subtract x from both sides
2x-160=20
Add 160 to both sides
2x=180
Divide both sides by 2
x=90
