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.

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.

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.
