First find the value of the two vertical angles which have x in them.
Vertical angles are the same so you have:
4x = x +36
subtract 1x from each side:
3x = 36
Divide both sides by 3:
x = 36/3
x = 12
Now replace x with 12 to solve for the angles:
4x = 4(12) = 48 degrees.
All 4 angles need to equal 360 degrees, so now subtract 48 +48 from 360:
360 - 96 = 264
Y and the angle above it are vertical angles, so you can divide 264 by 2 to find y:
Y = 264 /2
Y = 132 degrees.
