Answer:

Explanation:

Given are parallel lines e and f

Also given that angle 3 =120 and angle 12 =80

Two transversals cut them

By axiom of parallel lines we have corresponding angles equal, alternate angles equal and interior angles are supplmentary

Using these we get

1= 180-120 =60

2=120: 4=60: 5=60: 6=120:7=120 and 8=60

Similarly for other transversal we get

10=100:13=80:10=100:14=100

Hence all are right except 6 and 10.
