It actually should have been 120<y<125

Looks like you had no chance with that question.

Okay. Are you able to explain why how you would get that answer?

Because x + y = 180 since x and y are supplementary. Therefore if the values of x are between 55 and 60, the values of y must be between 120 and 125

firstly the question hasn't been proof read very well... the V should be B 55<y<60 then x will be in the solution x and y are supplementary... meaning that add to 180 degrees' the question is saying if 55<y< 60 or if y is between 55 and 60 degrees, between what measurements is x if y = 55 then x = 125 55+125 = 180 y = 60 then x = 120 60 + 120 = 180 so the solution is if y is an angle between 55 and 60 then x must be between 120 and 125 e.g. y = 57 x = 123

Aha! That makes sense! Thanks so much for the thorough answer, campbell_st

Actually, since y is obtuse, the solution should have been 120<y<125
