Question 744983
A right triangle is formed with two legs of 6√2 ft and the diagonal as the hypotenuse.


a² + b² = c²   {the Pythagorean Theorem}
(6√2)² + (6√2)² = c²   {substituted 6√2 in for the legs, a and b}
36(2) + 36(2) = c²   {evaluated the exponents}
72 + 72 = c²   {multiplied}
144 = c²   {added}
c = 12   {took the square root of each side}
