Question

please step by step Ans ​

Answer 1

Answer:

y = 80° x =100° z = 100°

Step-by-step explanation:

We have,

y = 80° (since vertically opposite angle)

Also,

y + z = 180 ( since linear pair)

so, angle z = 100°

And ,z=x=100° (since vertically opposite angle)

Answer 2

Answer:

y=80°. (vertically opposite angle)

y+x=180°. (linear pair)

=80+x=180

x=180-80

x=100°

x=z ( vertically opposite angle)

so, z=100°
