So supplement angles are angles that add up to 180 so
so x=180-y it's kind of hard to represent the problem but this is my way (which is basically trial and error and math stuff (confusing) and uses luck) so x=21+2y x+y=180 so since the above equations are true then ((180-21)/3)=53= supplement=53
angle=127 supplement=53
trial and error and accient 127=21+2(53) 127=21+106 127=127
