the order of the size of angles is related to the order of the length that is opposite to that angle.
angle A is across from the smallest side, 2.4.
angle C is across from the middle side, 3.2
angle B is across from the longest side, 5.5
if you think about it, angle B has to be widest angle for it to accommodate the longest length (longer it is, the more you have to open). anlge A has to be the smallest angle for it to correspond with the smallest length
The order of smallest to largest is ∠A, ∠C, ∠B
