Question

two supplementary angles differ by 20 degree. find the angles​

Answer 1

Answer:

We know that, sum of two supplementary angle is 180°. i.e. The smaller angle is 100-20=80°.

Answer 2

Answer:

100° and 80°

Step-by-step explanation:

let the supplementary angles be 'x' & 'y'

x+y= 180° ----------(1)

x-y= 20° ----------(2)

add equation (1)&(2)

x+y+x-y= 180+20

2x= 200

x= 100°

x-y=20

100-y = 20

-y= 20-100

-y= -80

y=80°
