VX|YZ is given.
21 24 and 23 25 because alternate interior angles of parallel lines are congruent.
Then, m/1 = m/4 and m/3 = m/5 because congruent angles have equal measure.
What is the equation that can be used for the next step in the proof?
O A. m/1+m/2+m/3+m/4+m/5 = 180°
O B.
m/1+m/2+ m/3 = 180°
O c.
m/4+m/2+m/5 = 180°
O D. m/1+mZ3+ m24+ m25 = 180°
