Okay, here we have this:
Considering the provided information, we are going to use the Pythagoras theorem, so we obtain the following:
[tex]\begin{gathered} h^2=c^2+c^2 \\ h^2=3^2+5^2 \\ h^2=9+25 \\ h^2=34 \\ h=\sqrt[]{34} \\ h\approx5.83 \end{gathered}[/tex]Finally we obtain that length of the hypotenuse is approximately 5.83
