the answer is c
a pythagorean tripple refers to a set of numbers that fits the equation a^2 + b^2 = c^2
we know that c must be the biggest number and it doesnt matter which of the other ones is a or b
therefore we substitute the options into the equation and tge one that doesnt work is c 15, 18, 21
