For the figure, a // b. Solve for x

Question

Answer 1

The two angles are supplementary ( they add up to 180 degrees.

Answer 2

Hi Beaux S

x = 25

In the figure I think you were trying to indicate that line a is parallel to line b, and there is a transversal line crossing lines a and b. If so, then the measure of angle 2x + 30 is supplemental to the measure of angle 4x.

2x + 30 +4x = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 25

Checking

2(25) + 30 + 4(25) = 180

50 + 30 + 100 = 180

I hope this helps please let me know if I have interpreted the wording of your question correctly.
