Question

Which of the following could be the side lengths of a right triangle?

Answer 1

Recall that in a right-triangle, the hypotenuse, or longest side, is √(a²+b²).

$\bf \sqrt{4.1^2+6.2^2}\qquad \approx\qquad 7.43303437 \\\\\\ \sqrt{40^2+60^2}\qquad \approx\qquad 72.1110255 \\\\\\ \sqrt{3.2^2+5.4^2}\qquad \approx\qquad 6.27694193 \\\\\\ \sqrt{33^2+56^2}\qquad =\qquad 65$
