The diagonal is the hypotenuse of a right triangle with one leg 4 ft and the other leg 8 ft
a%5E2%2Bb%5E2=c%5E2 where a and b are legs and c is the diagonal
4%5E2%2B8%5E2=c%5E2
16%2B64=c%5E2
80=c%5E2 find square root of each side
sqrt%2880%29=c ANSWER The diagonal of the pool table is sqrt%2880%29=8.9 ft
