Of three angles, two are supplementary and two are complementary.
The sum is 220 degrees.
How do you find the measure of each angle?

So think of a 220 degree angle cut into three smaller angles. The left angle (x) and the middle angle (y) are complementary. The middle angle and the angle on the right (y) are supplementary.
x + y = 90
y + z = 180
x + y + z = 220
90 + z = 220
z = 130
y = 50
x = 40
x + y = 90
y + z = 180
x + y + z = 220
90 + z = 220
z = 130
y = 50
x = 40
