Question

Difference between 2suplementry angles is 20 degree find their degree mesurment

Answer 1

Answer:

Step-by-step explanation:

x+y=100

x-y=20

x=y+20

y+20+y=180

2y=180-20

y=80

x=y+20

x=80+20

x=100

Answer 2

Supplementary angle means their sum is 180

Let x and y be the angles
Then x + y = 180
Given x - y =20
Adding these two we get 2x=200 or x=100
So y=80
