ANSWER:
80
60
REASON:
1)Any angles opposite eachother is a cross with straight lines are equal. Therefore angle DOE is also 40. We know DOF is 120 so EOF must be 120-40=80 (which is DOF-DOE). BOC is opposite EOF so it also equals 80.
2) We know that angles on 1 straight line equal to 180 degrees. And we have to angles on a straight line but we are missing one which is COD. So we do (180-BOC-the angle we are given) 180-80-40= 60
