1.
When two parallel lines are intersected by a transversal, the alternate interior angles are supplementary. Meaning that their angle measures add up to 180 degrees. Set up an equation and solve for the unknown angle using inverse operations.
2.
When two parallel lines are intersected by a transversal, the corresponding angles are congruent, in other words, they have the same angle measure.
