Question

Find a and b when two parallel lines are cut by a transversal.

Answer 1

Answer:

a = 60 degrees(alternate interior angles)

b = 120 degrees(allied angles)

Answer 2

Answer:

we know that corresponding angles be same

soverticak opposite angle of A be 60

then a also 60

$vertical \: opposite \: angle$

when a straight line be 180

then a+b=180

60+b=180

therefore b=120
