Answer:
5. 120
6. 125
Step-by-step explanation:
5. Since AB is parallel to CD
=>Angle(ABC) = Angle(ECD)
=> Angle ECD= 60
Angle ECD + Angle FEC= 180
=> Angle FEC = 120
6. Since l is parallel to m
=> Angle 2 = Angle 6
and,
Angle 6 = Angle 8
Therefore Angle 8 = 125
and therefore Angle 2 = Angle 8
Plz mark brainliest if answer is correct. And plz follow me

Answer:
5. 120 degree
6. Angle 2 = Angle 8
Step-by-step explanation:
5. Angle ABC = BCD (alternate int. angles). So, Angle BCD = 60 Degree.
60 degree + angle x = 180 degree (linear pair).
x = 180 - 60 = 120
x = 120.
6. Angle 2 = Angle 6 ( corresponding angles ).
Angle 6 = Angle 8 ( Vertically opposite angles ).
So Angle 2 = Angle 8
