Answer:

Angle BOC is 80 degrees

Angle COD is 60 degrees

Answer:

∠ BOC = 80°, ∠ COD = 60°

Step-by-step explanation:

∠ AOC = ∠ DOF = 120° ( vertical angles ), then

∠ BOC = ∠ AOC - ∠ AOB = 120° - 40° = 80°

-----------------------------------------------------------------

∠ COD = 180° - ∠ AOC = 180° - 120° = 60°
