1/2 = 0.5
74 & 1/2 = 74 + 1/2 = 74 + 0.5 = 74.5
The complement to this angle is 90 minus the angle, so,
complement = 90 - angle
complement = 90 - 74.5
complement = 15.5
Convert this to a mixed number
15.5 = 15 + 0.5 = 15 + 1/2 = 15 & 1/2
If the given angle is 74 & 1/2 degrees, then the complement is 15 & 1/2 degrees
Answer: 15 & 1/2 degrees

180 is the given angle. The supplement, let's call it x, will add to the given angle to get 180.
x+180 = 180
x+180-180 = 180-180
x = 0
So if we add 0 to the given angle 180, we get the result 180
Answer: 0 degrees
