Question

A pair of parallel lines cut by a transversal ,find a and b.​

Answer 1

Answer:

a = 50

b = 130

Step-by-step explanation:

In a transversal Interior angles on the same side are equal to 180

130 + a = 180

a = 180-130

a = 50

130 and b are vertically opposite angles and

vertically opposite angles are equal

Thus b=130

HOPE THIS HELPS

Answer 2

Answer:

a+130= 180

( interior angle test)

a= 50

B+ 130= 180

( opposite angle)

B=50
