complementary=angles add up to 90
so (im guessing you meant 28) if b is 28 then 90-28 is 62. m
supplementary=angles add up to 180
so if b is 137 then to find a subtract 137 from 180. a=43
by the definition of supplementary, the equation for #3 would be 2x+12+4x-42=180 because the 2 angles equal 180. adding like terms you get 6x-30=180. subtract 30 from each side, which gives you 6x=150. divide both sides by 6, giving you 25 degrees. since x is 25, to find m

1) Complementary means the angles add up to be 90 degrees. 90-28= 62
2) Supplementary means the angles add up to be 180 degrees. 180-137= 43
3) I have no idea
