I think there's something wrong here. As the angles formed by the diagonals of a rectangle and the length are equal, angle FAB should be 37 degrees and, as angle FAB isn't 0, the answer is obviously 53 degrees, but it's been set to 37 degrees for reasons beyond my comprehension.
Ans 3:

Edit: Angle AFB isn't 0 degrees either.
