Question

two supplementary angles differ by 20 degree the smaller of the two measure

Answer 1

let one angle be x
and other be x-20
x +x -20=180
2x= 180+20
2x = 200
x=100
other angle Will be 100-80 =20

Answer 2

Smaller of supplementary angles = 80°   if they differ by 20°

Step-by-step explanation:

Let say Smaller Angle =  A

Then Another Angle = A = 20

Sum of two supplementary angles = 180°

=> A + A + 20 = 180°

=> 2A = 160°

=> A = 80°

Smaller of supplementary angles = 80°
