I'm quite certain that you would not need to determine the angles in pythagorean triplets. This would require sine, cosine and tangent ratios . . . and either a calculator or a table of trig ratios. This question is outside the scope of the GMAT.

However, for the GMAT, you would need to know that the angle opposite the longest side is the largest angle, and the angle opposite the shortest side is the smallest angle
