Use the image to answer the question.
An illustration shows two parallel slanting lines m and l intersecting a vertical line k. The angles formed at the intersection of lines l and k are 1, 2, 4, and 3. The angles 1 and 4 are opposite to each other while angles 2 and 3 are opposite to each other. The angles formed at the intersection of lines m and k are 5, 6, 8, and 7. The angles 5 and 8 are opposite to each other while angles 6 and 7 are opposite to each other.
What is m∠1 if m∠4=25° ?

1 answer
Since angles 1 and 4 are opposite to each other, they are congruent. Therefore, if m∠4 = 25°, then m∠1 = 25° as well.
