The renowned architect and graduate of the MIU School of Design, Drew
Atower, designed a hotel, all of whose floors spin on a circular track. As it
spins, each floor pauses every 45°. (Otherwise, getting on and off the elevator
would be tricky.) The figure below shows an overhead view of one of the
square floors and its circular track. Points A, B, C, and D are located at each
of the four corners of the building. AO bisects ZW. Z, O, and X are collinear.
A, O, and C are collinear.

above the front entrance. One of the stained glass window designs being
considered has a radius of 90 cm and several wrought iron chords each
60 cm long. How far are the chords from the center of the circle? Draw a
diagram and show your work.
