Answer 2

Answer:

Though the question ain't stated properly.

I'm answering this from what I think the question seems to ask.

Step-by-step explanation:

Since, the lines are parallel.

Therefore, a= 78° (Corresponding Angles)

Similarly, c= (180-78)°= 102° (Co-interior Angles)

And, hence b= 102° (Vertically Opposite Angles)

Hope you get this!!
