The hypothenuse of a right triangle is calculated as:
[tex]hypothenuse=\sqrt{a^2+b^2}[/tex]
Where a and b are the other two sides of the right triangle.
In this case, a=5 and b=12, then the hypotenuse is:
[tex]\begin{gathered} hypothenuse=\sqrt{5^2+12^2} \\ hypothenuse=\sqrt{25+144} \\ hypothenuse=\sqrt{169} \\ hypothenuse=13 \end{gathered}[/tex]
Then, the answer is that the hypothenuse has a lenght of 13.
