Answer:
x = 4
Step-by-step explanation:
By the Alternate Exterior Angles Theorem, we know that the 2 given angles are equal to each other:
22x + 2 = 90
22x = 88
When lines are parallel, alternate exterior angles are congruent. That means that the bottom left angle is 90 degrees. Thus, 22x + 2 = 90. Basic math then proves that x = 4.
