Answer 1

Answer:

c = 130⁰

by linear pair.

plz mark my answer as brainleist answer.

Answer 2

Answer:

c=130

Step-by-step explanation:

Let a=4x and b=5x

We have,

a+b+Poy=180 (Straight line)

4x+5x+90=180

9x=180-90

9x=90

x=10

So,b=5*10=50

Now,

YON=b (Vertically opposite Angles)

YON=50

c+YON=180 (Straight line)

c+50=180

c=180-50

c=130
