You have the EXACT same textbook as me!Karma said:

This question is actually really easy once you understand a couple key things. You must first draw a diagram, and remember your arrows on your vectors. Also, it is a common misconception that for these types of problems the compression force is inwards (so in this case toward the building). Actually, the force is outwards. Once you realize this you can simply set up your vectors forming a right angle triangle...use trig to solve.

Post the steps you have, I'm not going to give you the answer, so I'll check your work with mine (my math teacher confirmed mine is correct). Good luck.
