Question

For what value of x is line a parallel to line b?

Answer 1

Corresponding angles must be equal

`\\ \tt\hookrightarrow 4x+28=116`

`\\ \tt\hookrightarrow 4x=116-28`

`\\ \tt\hookrightarrow 4x=88`

`\\ \tt\hookrightarrow x=22`

Answer 2

x = 22

Explanation:

4x + 28 = 116 (corresponding angles are equal when two lines are parallel)

4x = 88

x = 22
