hi please help me with this angles work for math class

Answer:
Angle A:60
Angle B:120
AngleD:60
Angle E:60
Angle F:120
Angle G:120
Angle H:60
Step-by-step explanation:
There are supplementary angles that add up to get 180 so 120+ __=180
60 is the missing Angle of A and D and since the lines are parallel and we also have vertical angles. The angles are going to be either 120 or 60
