It would be 67.
This is because 113 and x must add up to 180. Since the quadrilateral has equivalent and has 2 parallel sides, you are able to treat x and 113 as supplementary angles. Thus allowing you to set up an equation like this:
x + 113 = 180
Answer:
Step-by-step explanation:
it is a parallelogram.
x+113=180
x=180-113=67°
