The answers would be: x=93 and y=111
To find x, first find the missing angle measure of the triangle: 180-(68+25) = 93
You can then find the measure of x by subtracting 93 from 180.
To find y, find the sum of the missing angle measures in the middle quadrilateral. 360-(66+72) = 222.
Because the missing angle measures are equal to eachother, just divide by 2 to find the angle measure of y.
