Answer: A) 6
Explanation:
This is geometry. The two angles are corresponding angles, because they are both cut by the same **transversal line**. When that occurs, corresponding angles are created.
now importantly: corresponding angles are equal to each other, or **congruent**. Knowing this, we can set them equal to each other.
