One leg of a right triangle has length 7, and the triangle's hypotenuse has length 9. what is the length of the other leg, expressed in radical form?

Step-by-step explanation:

We have Pythagoras theorem,

      Hypotenuse² = Base² +  Perpendicular²

Here we have

        Hypotenuse = 9

        Base = 7

Substituting

      9² = 7² +  Perpendicular²    

      Perpendicular² = 81 - 49

      Perpendicular² = 32

Length of the other leg, expressed in radical form is
