The answer to your question is: x = √ 133

Step-by-step explanation:

This is a right triangle, so let's use the pythagorean theorem,

                        c²  =  a²   +   b²

c = 13

a = 6

b = ?

Substitution

                     13² = 6² + b²

                     169 = 36 + b²

                     b² = 169 - 36

                     b² = 133

                     b = √133 = x
