You know that all the angles in a parralelogram add up to 360 degrees, you also know that opposite angles are equal. 

This means that angle E= Angle G

3x+5=108

Once you solve for x:

360-3x+5-108=3y

You can then solve for y.

So after I solve for X what would I do because im not completely understanding

chaise · Answer

Once you solve for x, substitute it in to the equation:

360-3x+5-108=3y

And then solve for y.

anonymous · Answer

So: 
360-3(34.33)+108=3y ?

chaise · Answer

Yes.

chaise · Answer

y should equal 121.67 degrees

anonymous · Answer

Yeah thats what I got so would that be my final answer?

chaise · Answer

Well it asks for the value of y, and you just found it. 

I guess you could write: The value of y is 121.67 degrees.
