Plz answer Fasttttttt.....

Answer 1

Step-by-step explanation:

let the angle be 'x'

it's supplementary angle=180-x

ATQ, x=1/9(180-x)

x=20-x/9

x+x/9=20

10x/9=20

x=20*9/10

=18 degree

so required angle is 18 degree

Answer 2

Answer:

20

Step-by-step explanation:

supplementary angle has 180 degree

=1/9×180

=180/9

=20
