The sides of a triangle are 11, 5, and x. Find the set of all possible values of x.

Hint: If a and b are the two known sides, then the possible values for x is: |a - b| < x < |a + b|

I put x>6<16 the first time and I got it wrong lol. So is the correct answer 6<x<16?

hero (hero):

Yes. By the way, x>6<16 makes no mathematical sense

Oh well then I know why I got it wrong! Thank you! (:
