Given
∠B = 47° (lowest)
∠C = 72° (highest)
∠A = 180° - (72°+47°) = 61° (middle)
The sides opposite to the angles corresponds to their length.
We have the following:
∠A corresponds to side BC
∠B corresponds to side AC
∠C corresponds to side AB
Therefore, the order of the sides from shortest to longest is AB, BC, AC
