In the figure, a || e, m || n, and m/3 = 112°. What is the m/1? Enter your answer in the box.

Answer:
∠ 1 = 112°
Step-by-step explanation:
Since m and n are parallel lines then
∠ 2 and ∠ 3 are corresponding angles and congruent, that is
∠ 2 = ∠ 3 = 112°
∠ 1 and ∠ 2 are vertical angles and congruent, thus
∠ 1 = 112°
