Answer/Step-by-step explanation:
✔️m<1 + 52° = 180° (consecutive angles angle)
m<1 = 180 - 52
m<1 = 128°
✔️m<2 = 52° (alternate interior angles are congruent)
✔️m<3 = 47° (alternate interior angles are always equal)
✔️m<4 + 47° = 180° (consecutive angles)
m<7 = 180 - 47
m<7 = 133°
✔️m<5 = 180 - (52 + 47)
m<5 = 180 - 99
m<5 = 81°
