Assuming one leg is (a) and the hypotenuse is (c),the formula we will use for a right-angled triangle is:
where b is the length of the third side.
We plug the values into the equation,
The length of the third side is or b ~ 7.21 cm.
To show how you obtained the answer :
b =
We separate as ---> since 4 x 13 = 52.
We know that and cannot be simplified so we keep it and,
b = or b ~ 7.21cm.
