Question

if angle A and angleB are supplementary angles and the angle B=(x+20),then what would be the angle A​

Answer 1

Answer:

let the angle a be x

x+x+20 = 180

2x+20 = 180

2x = 180-20

2x = 160

x = 80

angle A = 80

angle B = 80+20 = 100

Answer 2

Answer:

I hope it will help u

Step-by-step explanation:

x+x+20 = 180

2x+20 = 180

2x = 160

x = 80

angle A = 80

angle B = 80+20 = 100
