Question 78384
Here hypotenuse = 12
one leg = 8
the other leg = sqrt(12^2 - 8^2) [by Pythagorean theorem]
              = sqrt(144 - 64)
              = sqrt(80)
              = sqrt(16*5)
              = sqrt(16) * sqrt(5)
              = 4 * sqrt(5)
Thus leg b = 4sqrt(5)which is in simplified radical form.
