Taking into consideration the quadrilateral, getting rid of the oblique line that is just to make the question trickier, we have that its internal angles must sum to 360. Thus, we can say that 2x + 110 + 50 = 360 and thus x = 100.

Another alternative to the problem
If we consider the 5 sided polygon in the center and sum of the interior angles will be (n-2)*180 = (5-2)*180=540 degree.
Now adding the angles in the polygon we have = 110 +2x +(180-a)+(180-b) =540
or 2x = 70+a+b
or x = 200/2 = 100 (since in the triangle of angle 50,a,b we have a+b+50 =180 or a+b = 130)
