Remember that a 4-sided polygon must have (4-2)*180 = 360 degrees total. To find x+y, it would be sufficient to find the sum of interior angles opposite x and y, inside the 4-sided polygon. The answer is C. I go through the question in detail in the full solution below (taken from the GMATFix App).
