## LyraElizabethAdams 3 years ago Hi, I don't understand this question (attached). Would you please explain why the answer is: 120<x<125?

2. Hero

It actually should have been 120<y<125

3. Hero

So even I would have gotten it wrong

4. Hero

Looks like you had no chance with that question.

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

6. Hero

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

OH, I see! Okay, thank you very much! :)

8. Hero

@campbell_st must be typing a book

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

12. Hero

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

Okay

Thanks so much!
