Question

What is the answer for x

Answer 1

x = 4

Explanation:

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.

Answer 2

x = 4

Explanation:

By the Alternate Exterior Angles Theorem, we know that the 2 given angles are equal to each other:

22x + 2 = 90

22x = 88

x = 4
