Step1: Apply the Pythagorean theorem
Let the third side be \(x\). According to the Pythagorean theorem \(a^{2}+b^{2}=c^{2}\), where \(c\) is the hypotenuse. Here \(c = 23\), \(a=13\), and \(b=x\). So \(x^{2}+13^{2}=23^{2}\).
Step2: Solve for \(x^{2}\)
\(x^{2}=23^{2}-13^{2}\). Calculate \(23^{2}=529\) and \(13^{2}=169\). Then \(x^{2}=529 - 169=360\).
Step3: Solve for \(x\)
\(x=\sqrt{360}\approx18.97\) (rounded to two decimal places).
