that if a support rope on the side of a tent is placed at a 45degree angle to the ground, it will provide maximum support for the tent.
a) How far away from the base of your 6-foot tent wall should you 8ft rope be placed in order to provide maximum support in a strong wind.
This is what I got:
sinC/8=sin45degre/6
sin angle C=70.5 so the 180 - (45+70.5)=64.5.
Sin64.5degree/a=sin45degree/6
The rope should be 7.66 feet away from the base of the tent.
What I don't know how to figure out is the second part:
b) As the tent size changes, so does the length of the wall, the length of the support rope, and the maximum support angle. Derive a general formula that will allow you to determine how far away from the base of the tent wall the end of the support rope should be. Now this is an oblique tent so there is no 90degree angle. Can anybody help figure this out?

This is a pre-calc question that I am trying to figure out. This is not for my own tent. I need to figure the formula in part b for homework, please help! I don't know where to start!
