Question

Hi, I don't understand this question (attached). Would you please explain why the answer is: 120 14 years ago

Answer 1

It actually should have been 120<y<125

Answer 2

So even I would have gotten it wrong

Answer 3

Looks like you had no chance with that question.

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

@campbell_st must be typing a book

Answer 8

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

Answer 9

:)

Answer 10

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

Answer 11

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

Answer 12

Okay

Answer 13

Thanks so much!
