Question: 
In the first column, the given side lengths specify a right triangle $ABC$ with a right angle at vertex $C$ (see the picture). In the other two columns, the measures of the angles at vertex $A\ (\alpha)$ and vertex $B\ (\beta)$ are given, rounded to whole degrees. Match each triangle to the measures of its angles $\alpha$ and $\beta$.
