The correct response is:
He did not set up the Pythagorean Theorem correctly. The hypotenuse should be isolated on one side of the equation.
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c²) is equal to the sum of the squares of the lengths of the other two sides (a² + b²). Thus, it should have been set up as \(c^2 = a^2 + b^2\), not the way it was presented in the first equation.
