Comlement is the angle that adds to 90

supplement is the one that adds to 180

x+c=90

x+s=180

solving for s and c

minus x frmo both sides in both equations

c=90-x

s=180-x

c (x) = 90-x

s (x) = 180-x

the domain has to be the numbers that make c (x) positive (assuming you haven't taken trig)

also, the angle cannot be negative

so x>0

solve for where it equal 0

for c (90) that is the zero and s (180) is the other zero

range is from 0 to the end

c (x) = 90-x

domain is from 0 to 90

range is from 0 to 90

s (x) = 180-x

the domain is from 0 to 180

range is from 0 to 180
