Q:
# For what value of x is line a parallel to line b?Enter your answer in the box.x =

Accepted Solution

A:

It will be parallel only if angle (2x + 20) equal to 80, or (2x + 20) + 100 equal to 180. Let's use the first example:

1) 2x + 20 = 80

Subtract 20 from the each side:

2) 2x = 80 - 20

3) 2x = 60

Divide everything by 2:

4) 2x/2 = 60/2

5) x = 30

So, the answer will be x = 30. Hope this helps!
