1. The problem statement, all variables and given/known data Problem 4: http://www.nspsmo.org/_data/global/images/2010-11%20Sample%20Problems.pdf [Broken] 2. Relevant equations Second to last page in same document. 3. The attempt at a solution I know how to solve everything but the minor chord lengths: CD, DE, EF The only thing I could think of was to do something similar to problem 3, using C to the bottom left corner and its adjoining leg (and do the same for each chord), but I don't think I can solve the problem that way. Any help is appreciated!
