Examine Carmen’s rail plans to identify the measure of ∠1. The streets represented by lines V and W are parallel. What is the m1?25°35°145°155°

Sample response: Angle 2 is a supplementary angle with 17°, so m∠2 = 163°. Since ∠1 and ∠2 are alternate interior angles of parallel lines, they are congruent, and the m ∠1 = m ∠2. Thus, m∠1 = 163°.
