Hinge Theorem: If two sides of two triangles are congruent, the angle opposite the smaller of the remaining side of the two triangles must be less.
Since the angel x-13 is opposite side length 22 and 75 is opposite side length 23, x-13 has to be less than 75. Since the angle must also be greater than 0, we get the inequality:
0 < x - 13 < 75 ---> 13 < x < 88.
