Question

I have to find x but I am not sure how to? ​

Answer 1

Supplementary angles add to 180

So, the angle supplementary to the angle of 112 degrees measures 68 degrees.

If these two lines are parallel, the angles are the same.

So, the triangle has angle measures: 2x, 68, and 68.

2x+68+68=180

2x=44

x=22

Let me know if this helps!
