Question

two supplementary angles differ by 20 what is the measure of smallest angle​

Answer 1

Answer:

80

Step-by-step explanation:

Sum of supplementary angles = 180°

Let the one angel be X

Other angle = 180°-x

A/Q 180°-x -x = 20

180°-2x =20

-2x = 20-180

-2x = -160

x = -160/-20

= 80

Two angles are 80°and 100°

And smallest angle is 80°
