Lines a and b are parallel and lines e and f are parallel.
If M1 = 89°, what is M5

Answer:
m∠5 = 91°
Step-by-step explanation:
Linear angles 1 and 2 are supplementary; alternate interior angles 2 and 3 are congruent, as are corresponding angles 3 and 5. Hence angles 1 and 5 are supplementary.
m∠5 = 180° - m∠1 = 180° -89°
m∠5 = 91°
