A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88
Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
You would take the answer of the square root problem and find the number that you can multiply by its self that would make that answer correct.
