Answer:   12

Step-by-step explanation:

To find a length of a right triangle, we can use Pythagorean theory:

            leg² + leg² = hypotenuse²              

                  5² + b² = 13²

                 25 + b² = 169

                          b² = 144

                            b = [tex]\sqrt{144}[/tex]

                             b = 12
