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°
