Question 1107304
Description seems clear enough.  Two intersecting lines. There are four angles.  The top, the left, the right, and the bottom.


Top and Bottom are VERTICAL ANGLES and vertical angles are congruent.
This means {{{2y+6=8y-102}}}, and you can solve for y.


The left angle is 3x degrees.
What?  No "angle on the right of it"?  
The 3x angle is supplementary to either the 8y-102 degree angle or the 2y+6 degree angle.


THAT means that   {{{3x+8y-102=180}}}, and {{{3x+2y+6=180}}};
and you should have already solved for y.
