Hint
Help VideoCorrect
Nice Job!
Incorrect
Supplementary angles are when two angles have a sum of `180°.` Typically, these angles lie on a straight line.Since supplementary angles add to `180°,` add the angle measures and set their sum to `180°.` Then, solve for `y`.`y+118` `=` `180` `y+118` `-118` `=` `180` `-118` Subtract `118` from both sides `y` `=` `62°` `/_ y=62°` -
