Answer: option 3

Step-by-step explanation:

M1:

180° = 69° + 31° + M1

-M1 = 69° + 31° - 180°

-M1 = -80°

M1 = 80°

M2:

180° = 45° + 31° + (M2 + 69°)

180° = 145° + M2

-M2 = 145° - 180°

-M2 = -35°

M2 = 35°

M3:

180° = 69° + 47° + (M3 + 31°)

180° = 147° + M3

-M3 = 147° - 180°

-M3 = -33°

M3 = 33°
