You can put this solution on YOUR website! In a parallelogram adjacent angles are supplementary. From above we have
(i)
(ii)
we can solve for y in (ii) as
(iii)
then
(iv)
dividing, we get
(v)
Now we can solve for x in (i) as
(vi)
combine like terms to get
(vii)
subtract to get
(viii)
and divide to get
(ix)
