x = 14

Answer:

x = 14

Step-by-step explanation:

This quadrilateral is a parallelogram. Due to this, opposite sides are congruent. One side is 17, that means the opposite side is 17. We can write this as the equation

x + 3 = 17.

If we subtract 3 from both sides, we isolate the variable x.

x = 14.

Therefore, x = 14
