Question

Find the value of x to make A||B

Answer 1

X=90 you have to make the two equations equal

Answer 2

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
