Question

If m∠3=63°, find m∠1
Show work.

Answer 1

Since m∠3 = 63° and m∠1 is corresponding angles (being on the same 180° line and they correspond each other), then m∠1 is also equal to 63°

Explanation:

m∠3 = m∠1

Corresponding angles (one that holds the same relative position as another angle somewhere else in the figure)

Answer 2

63 degrees as well because its a line intersected by two parallel lines
