Answer:

x = 13

Step-by-step explanation:

As given , the triangle is right angle . So we can use

Pythagoras theorem

       ⇒  a² = b² + c²

            a² = (12)² + (5)²

           a² = 144 + 25

          a² = 169

           After taking square root

            a = 13

    So  

         x = 13
