When a parallelogram is folded as shown, notice a kite is formed. Hence, the opposite angles are the same as shown in red and blue markings.

We will need to find the angle y, then the angle x.

With the property of a parallelogram, we have
32 + y + y + 104 = 180
y = 22

104 + x + y = 180
so, x = 180 - 104 - 22 = 54 degrees
