Step-by-step explanation:
The measure of smallest angle is 80°.
Step-by-step explanation:
Let the larger angle be 'x'.
So the smaller angle is 'x-20'.
We know that, sum of two supplementary angle is 180°.
i.e. x+x-20 = 180x+x−20=180
2x-20 = 1802x−20=180
2x=180+202x=180+20
2x=2002x=200
x=\frac{200}{2}x=

x=100x=100
The smaller angle is 100-20=80°.
