Homework Help: Question using the Sine Rule and Bearings

  1. Aug 30, 2012 #1
    1. The problem statement, all variables and given/known data
    3 towns are located at D,F & E; the vertices of an scalene triangle. The bearing of F from D is 48 degrees. D to E=640m and E to F=430m. Point G is located at the end of a south line at F.

    a)i)Find angle DFG
    ii) Find angle GFE
    iii) Find angle DFE

    b) Calculate angle EDF
    c)Calculate the bearing of E from D
    d)What is the distance between D & F

    2. Relevant equations

    3. The attempt at a solution
    a)i) I got 48 degrees because I used a z-angle
    ii) This is the one I can't get so I can't do the rest. I've tried quite a few ways but can't seem to get it so there must be something I'm missing.

    I've got it now there was angle missing from the diagram :L
