Answer 1

First find the angle marked "?"
Then equate 2x + 5 to the angle marked "?" because for parallel lines they form corresponding angles.

Answer 2

Should be (2x + 6) above.

Answer 3

Is x 130?

Answer 4

No. The angle marked 130 and the angle I have marked with a "?" are supplementary angles and so they add to 180. So the angle marked "?" is 180 - 130 = 50.

Equate (2x + 6) and 50 (because they are corresponding angles) and solve for x.
2x + 6 = 50
Solve for x.

Answer 5

ah so x = 22
