Answer:
y = 69 and x = 104
Step-by-step explanation:
The sum of the interior angles in a 4 sided polygon is 360 degrees so
121 + 66 + x + y = 360
The sum of the angles on a line intersected by one point = 180
So we can find y by subtracting 111 by 180
180 - 111 = 69
y = 69
Plug 69 back into the other equation
121 + 66 + x + 69 = 360
x + 256 = 360
x = 104
Geometry is not my best subject but hopefully this helped!
