Question
**Transcription:** "If m ∠5 = 65°, then m ∠1 = _____." **Diagram Explanation:** The diagram shows two parallel lines, labeled B and C, intersected by a transversal line, creating eight angles at the intersections. Angles are numbered from 1 to 8 around the intersections. Line B intersects one side, and line C intersects the other, while the transversal cuts across both lines. Angle 5 is given as 65°. To determine the measure of angle 1, use the properties of parallel lines and corresponding angles; angle 1 is equal to angle 5 because they are alternate interior angles. Therefore, m ∠1 = 65°.
