Question 671882
Use the html tags < img > .. to post the image (like I did below)


<img src="http://s10.postimage.org/bjx5rrx53/Diagram.png">


Note: I typed in <  img src="http://s10.postimage.org/bjx5rrx53/Diagram.png"  > but without spaces (there's only one space between the 'img' and 'src')


From the diagram above, we're given f || g (ie lines f and g are parallel)


So the left transversal line makes two supplementary same side interior angles with measures 7x and 2x+36 degrees, so...


7x + (2x+36) = 180


7x + 2x+36 = 180


9x+36 = 180


Keep going to solve for x.
