Answer:
BC, CA, AB
Explanation:
the measure of each angle is super important, bc you use it to compare the lengths of each side in this problem. the bigger the angle, the bigger the opposite side is. so, if you were to draw a line from the angle measuring 83 degrees, it would go to side AB. since the angle measure is the largest out of the three angles, it makes AB the largest side.
hopefully that makes sense!! :)
