Answer:
The square at angle EOG represents a right angle, meaning the angle there is 90 degrees.
Thus,
[tex]3y+27=90[/tex]
[tex]3y=63[/tex]
[tex]y=21[/tex]
The angles on a straight line add up to 180 degrees.
Therefore,
[tex]x+90+8x+18=180[/tex]
[tex]9x+108=180[/tex]
[tex]9x=72[/tex]
[tex]x=8[/tex]
