ivettef365 · Answer

Opposite angles of a parallelogram are congruent

anonymous · Answer

$$(3x+5) = 108$$
And
$$3y + (3x + 5) = 180$$

First solve for x in the first equation, then plug x into the second equation. Tell me if you have any problems ^_^

anonymous · Answer

The first equation I put is what @ivettef365 is talking about.

anonymous · Answer

3y = (180 - 108)....since adjacent angles are supplementary

anonymous · Answer

no need to involve X unless its required

anonymous · Answer

Blast my tendencies toward involving all possible routes. :P

ivettef365 · Answer

If you have that angle E = 108, then you know that angle G = 108
so you have 360 - 108 - 108 = 144
so angle D is half of 144

anonymous · Answer

haha, it happens!

anonymous · Answer

just remember adjacent angles are supplementary (add up to 180)  and opposite angles are congruent (equal)

anonymous · Answer

So Y is 72?

anonymous · Answer

3y = 72 ....  (the angle measurement is)....sounds like the question is find the y variable....so just finish solving!

anonymous · Answer

Not quite. You are forgetting one step in the simplification.

anonymous · Answer

Ah haha, So the answer is 24?

anonymous · Answer

Exactly ;D

anonymous · Answer

Thanks Guys!
