Question

Find the value of x that will make A||B.

Please help!

Answer 1

x=30

Explanation:

Hi there!

For A to be parallel to B, 5x would be equal to 3x+60. (If they were parallel, these two angles would be alternate exterior angles, which are equal.)

`5x=3x+60`

Subtract 3x from both sides

`5x-3x=3x+60-3x\\2x=60`

Divide both sides by 2

`x=30`

I hope this helps!
