Answer:

5

Explanation:

Sure! Because this shape is a parallelogram, that means EF and HG are parallel to each other, and EH and FG are parallel to each other!

Because they're parallel to each other, you know the opposite angles inside a parallelogram must always be equal to each other!

So, we know:

112 = 21x+7

x=5
