Question

given the information in the diagram, which theorem best justifies why lines j and k must be parallel?
converse alternate interior angles theorem
converse alternate exterior angles theorem

Explanation:

The 93 - degree angles are alternate exterior angles. The converse of the alternate exterior angles theorem states that if alternate exterior angles are congruent, then the two lines are parallel. Since we are given congruent alternate exterior angles and trying to prove the lines are parallel, this is the applicable theorem.
