Question

Can you answer my question please and thank you

Answer 1

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 = $\sqrt{144}$

                             b = 12

Answer 2

Answer:

b = 12

Step-by-step explanation:

since a² + b² = c²

we can find b by pythagorean theorem.

sqrt(13² - 5²) = b

hence,

b = 12
