Please help, it is similar to angles. halpp

Step-by-step explanation:

Because those 2 lines are parallel, then 2x + 10 and 2x - 30 are same side interior and are supplementary. Therefore,

2x + 10 + 2x - 30 = 180 and

4x - 20 = 180 and

4x = 200 so

x = 50

x = 50

Step-by-step explanation:

Two Parallel lines and an transversal.

Given angles are co - interior angles and they are supplementary.

2x + 10 + 2x - 30 = 180

2x + 2x + 10 -30 = 180   {Combine like terms}

4x - 20 = 180  

4x = 180 + 20     (Add 20 to both sides}

4x = 200              {Divide both sides by 4}

x = 200/4

x = 50
