Ans is C - X is 70
Using parallel lines, the shape can be divided into 2 and using the equations for angles in a polygon, the internal angle next to x can be evaluated as 110. Using the sum of angles on a straight line rule, value of x can be found as 180-110 = 70

C.
Draw a line extending from the 70 degree angle to the diagonal corner, and then youll have a triangle.
Next, you can infer that since you have the 70, the right angle, the corner angle must therefore be 180 - (90+70) = 180 - 160 = 20.
From there, we can then draw a straight line down from the top edge of the figure down to the point of our 70 degree angle. (making another triangle)
From there, we can see we've got 20 degrees from above, the 90 degrees we drew, and therefore the opposing angle to x is 180 - 110 = 70
