Question 919082
For HOW MANY VALUES of k?


{{{11^2+15^2>k^2}}},


Also need to apply this to the two other sides.
{{{11^2+k^2>15^2}}} and {{{15^2+k^2>11^2}}}



Not so much of how many values of k; but more important, which values of k.
Important rule here is {{{k>0}}}.


(1)
{{{k<18.601}}}

(2)
{{{k>10.20}}}

(3)
... k must not be negative.


k can be any value such that {{{highlight(10.2<k<18.601)}}}
