OpenStudy (callisto):

I am a student!

OpenStudy (anonymous):

wat grade?

OpenStudy (callisto):

Year 1. Just go back to the question you ask... To form a triangle, the sum of two sides must be greater than the third.

OpenStudy (anonymous):

no.

OpenStudy (anonymous):

i dont need your help thank you

OpenStudy (mayankdevnani):

apply the triangle inequality i.e sum of any two sides of triangle is greater than the third side. ok @monasamoneis

OpenStudy (callisto):

Since the length given are all smaller than the side 18 So, x+9>18 This inequality must be satisfied to form a triangle.

OpenStudy (callisto):

It's okay if you don't need my help. Good luck.

OpenStudy (anonymous):

ughh finally

OpenStudy (anonymous):

@mayankdevnani so wht did u say?

OpenStudy (mayankdevnani):

apply the triangle inequality i.e sum of any two sides of triangle is greater than the third side.

OpenStudy (anonymous):

so what would i have to do to do tht?

OpenStudy (anonymous):

18>x>9?

OpenStudy (mayankdevnani):

take first option i.e 10 and other two sides are 18 and 9

OpenStudy (anonymous):

so 10>18>9?

OpenStudy (callisto):

lol when I say go back to the question you ask, I mean this question... not the previous cosine one.. Anyway.

OpenStudy (mayankdevnani):

it has greater sum of other two sides.okk

OpenStudy (mayankdevnani):

OpenStudy (anonymous):

OpenStudy (mayankdevnani):

yaa i.e 9

OpenStudy (mayankdevnani):
