HI,
*Note: the sum of supplementary angles is 180 degrees
Let x be the angle asked for (the smaller one)
would be the other (it is 20 more than the angle in question)
.

.
simplify and solve for x

.

x = 80 degrees ( THE ANGLE ASKED FOR)
.
check Your answer:
(x + 2O) = 100 degrees (then the OTHER)
80degrees + 100degrees = 180degrees
