Question

If A and B are supplementary angles and B = x + 20 then what would be measure of angle A ?

Answer 1

Answer:

(160-x)°

Step-by-step explanation:

as A and B are supplementary angles

=> angle A + angle B = 180°

now angle B = (x+20)°

=> angle A + (x+20)° = 180°

=> angle A = (180-20-x)°

=> angle A = (160-x)°

Answer 2

Step-by-step explanation:

A+ B =180

A =X

B = X+ 20

X +X +20 = 180

2X +20=180

2X =180 -20

2X = 160

X = 160/ 2

X = 80

A 80

B =X +20

= 80 +20

= 100
