Hint:   Angle z  + 108   add to 180 degrees (a straight line)

Once you find z    all of the interior angles add to 360 ... so you can find y

Hey so I don't want to mess up what EP is trying to teach you but I can help you a little but not much What he said or ment was that you can can subtract 108 from 180 degree's because both angles are on a straight line if you do the following subtraction you will get z now after that all you need to do is find y so keep in mind what EP said that all inside angles add up to 360 degree's : )

\(108^{\circ} + z^{\circ} = 180^{\circ}\\ z^{\circ} = 72^{\circ}\\ z = 72\) (angles on a straight line adds up to 180 degrees)

 

\(z^{\circ} + y^{\circ} + 102^{\circ}+84^{\circ} = 360^{\circ}\\ 72^{\circ} + 102^{\circ} + 84^{\circ} + y^{\circ} = 360^{\circ}\\ y^{\circ} = 102^{\circ}\\ y = 102\)  (interior angle of a quadrilateral adds up to 360 degrees)
