Answer/Step-by-step explanation:
The question didn't specify which of the numbered angle we're to look for. However, let's find all the numbered angles.
✔️m<2 = 180° - 53° (linear pair angles)
m<2 = 127°
✔️m<7 = 180° - 53° (consecutive exterior angles are supplematry)
m<7 = 127°
✔️m<8 = 53° (alternate exterior angles are congruent)
