∠x and ∠y are supplementary angles ∠y measures 142 what is the measure of x

Supplementary angles add up to 180

⇒ ∠x + ∠y = 180

∠x + ∠y = 180

∠x + 142 = 180

∠x = 180 - 142 = 38°

x = 38°

no this is a nonlinear negative

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
