Question

two supplementary angles differ by 20° . find the measure of each angles with solution​

Answer 1

Answer:

80

Step-by-step explanation:

let one be x second x-20

x+x-20=180

2x=200

x=100

x-20=80

Answer 2

Answer:x = 100

y= 80

Step-by-step explanation: let the angles be x and y.

x + y = 180( supplementary angles )

x- y = 20 ( given )

solving equations we get

x = 100

y= 80
