For what value of X is line a parallel to line B?
(4x+28). 112. 68

Answer:
x = 10
Step-by-step explanation:
Same side interior angles are supplementary (SSIA theorem).
Set the equation equal to 180 then solve for x.
4x + 28 = 68
Solve
68 - 28 = 40
40/4 = 10
x = 10
Answer:
10
Step-by-step explanation:
112 + 4x + 28 = 180°
140 + 4x = 180°
4x = 180 - 140
x = 10
