OpenStudy (mathmate):

Hint: opposite angles of a parallelogram are congruent.

OpenStudy (mathmate):

and adjacent angles of a parallelogram are supplementary (means adds to a sum of 180 degrees)

OpenStudy (anonymous):

So I set the equation equal to 96?

OpenStudy (mathmate):

yep, and solve for y.

OpenStudy (mathmate):

By the way, which relation are you using?

OpenStudy (anonymous):

Relation? Also, how do I solve for y?

OpenStudy (mathmate):

adjacent angles of a parallelogram are supplementary (means adds to a sum of 180 degrees is what you are planning to use, I hope.

OpenStudy (anonymous):

Yes, thanks for your help.

OpenStudy (anonymous):

I still don't understand how to find y. I got 25 for x.

OpenStudy (mathmate):

Using "adjacent angles of a parallelogram are supplementary (means adds to a sum of 180 degrees" we see that 6y+96=180 degrees Solve for y.

Oh, ok. That makes sense, thank you.
