If A and B are the angles, then
A + B = 180
and
A - B = 20
So that 2A = 200 ie A = 100 and then B = 80
So the two angles are 100 and 80 degrees.

No, right angles are 90 degrees, supplementary and vertical angles are 180 degrees.
Supplementary angles add up to 180 degrees Complementary angles add up to 90 degrees So: 180-60 = 120 degrees
Supplementary angles are two angles which add up to 180°.
