Use the pythagorean theorem
a squared plus b squared equals c squared where c is the length of the hypotenuse and a and b are the lengths of the legs in a right triangle
c^2-b^2=31^2-23^2=432
432=a^2
a=approx 20.7846
IS calculation is not reasonable, first take all three totals and add them together. His total is $107.68, compared to his calculated $87.22 he is off by $20.64.
