The hospital and library are on the west side of the photo.
In hospital a, the angular terminal ray AO is obtained by taking the due south direction as the starting edge and rotating 60 counterclockwise.

In B calibration, take the true north direction as the starting edge, and rotate it clockwise for 45 degrees to get the angular terminal ray BO.

Then the intersection of AO and BO is point o, then point o is the location of the library.
