The given triangle is a right angle triangle.
The length of the hypotenuse of a right angle triangle can be determined by using Pythagorus theorm,
[tex]\begin{gathered} h=\sqrt[]{p^2+b^2} \\ h=\sqrt[]{5^2+5^2} \\ h=\sqrt[]{50} \\ h=5\sqrt[]{2} \end{gathered}[/tex]
Thus, the above expression gives the requried length of the triangle in the radical form.
