Answer:
[tex]y=55\\x=108[/tex]
Step-by-step explanation:
We know that the total angle sum of the quadrilateral internal angles is 360° since we are working with a quadrilateral polygon.
So when finding the interior angles we set up the equation of
[tex]125+y=180\\72+x=180[/tex]
Subtract 180 by 125 and 72 to find y and x
[tex]y=55\\x=108[/tex]
