Question: 
Consider triangle ABC, where |AB|=c, |AC|=b, and |BC|=a. Let α be the angle at vertex A, β be the angle at vertex B, and γ be the angle at vertex C. Three of the given sets of two side lengths and one angle measure specify a right triangle ABC with a right angle at vertex C. The side lengths and angle measures are rounded to one decimal place. Identify those sets.
