Carmen is planning rail lines for a new train station. Help her find m1. Explain how you found that solution.

Question illustration
Answer:

Angle 2 and the angle measuring 17° are supplementary because they form a linear pair, so m∠2 = 180° – 17° = 163°. Angle 1 and angle 2 are alternate interior angles, which are congruent when lines are parallel. Therefore, m∠1 = 163°.
