In △ ABC, the corresponding sides of angles a, B and C are x, B and C respectively. If △ ABC with B = 2 and B = 45 ° has exactly two solutions, then the value range of X is () A. （2，+∞）B. （0，2）C. (2，22)D. (2，2)

From the necessary and sufficient condition that a triangle has two angles, we can see that xsin45 ° B ＜ x, that is 22x ＜ 2 ＜ x, and the solution is 2 ＜ x ＜ 22, that is, the value range of X is (2,22)
