Trig Star question

  1. Apr 22, 2012 #1
    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!

    hi rebat! :smile:
    do you know the coordinates of D and E ?

    if so, then use pythagoras :wink:

    for E, you know the y coordinate of E, and you know the length AE,

    so the x coordinate is … ? :smile:

    I am disappointed I didn't see that!!!

    Thanks for the help :)
