Answer:
D. Supplementary
Step-by-step explanation:
Consecutive Interior Angles Theorem:
If two parallel lines are cut by a transversal, then consecutive interior angles are supplementary.
Supplementary means the sum of the angles is 180 degrees.
Another name for consecutive interior angles is same side interior angles. The angles are on the same side of the transversal (in this case to the left) and they are in between the parallel lines which is the interior.
