The correct answer is 90°.
In a rectangle, opposite angles are congruent, meaning they have the same measure. Since ∠XYA and ∠XBY are opposite angles and both measure 90°, then ∠XBY also measures 90°.
Similarly, ∠DYX and ∠DYB are opposite angles, so they also have the same measure. Therefore, m<XDY is also 90°.
