2. (10 points) A rectangular piece of paper $A B C D$ is folded and pressed flat in the manner shown in the right figure, so that triangle $D C F$ falls onto the position of triangle $D E F$, with vertex $E$ landing exactly on side $A B$. Given that $\angle 1=22^{\circ}$, then $\angle 2$ is $\qquad$ degrees.
【Solution】Solution: Since the fold, $\angle C F D=\angle E F D=90^{\circ}-22^{\circ}=68^{\circ}$, $\angle 2=180^{\circ}-68^{\circ}-68^{\circ}=44^{\circ}$.

Therefore, the answer is: 44 .
