    Recall that the Law of Cosines is: A^2 = B^2 + C^2 - 2BCcos(α) where α = angle opposite to the side of length A A = length of one side B, C = lengths of other sides To determine the angle measure in the triangle, we need angle to be unknown. Thus, we need three side lengths to be known, which corresponds to choice A.
