Question

The length of the hypotenuse of a right triangle is 137 units. The length of one leg of the triangle is
105 units. Gina wrote the following step to find the length of the unknown leg:
Length of the unknown leg = 1372 − 1052 = 18,769 − 11,025 = 7,744 units
Which statement best explains whether Gina's step is correct or incorrect?
