    Well, I spent 2 weeks worth of toilet and bedtime reading time to solve this @!$@#%@#$%# problem.

    I have already typed up the solution and will post it here in 2 weeks time.

    In the mean time, keep trying!

    the solution is simple. dont think too complex. all the methods except one is already discussed. and the remaining one is elementary.

    I got 30 deg. There are 3 triangles with the same angles and another 2 with another same set of angles. Am I right ?

    heh, if you think too deep and goes "&%^%(&%)*&", then you're most likely using the wrong method

    there's two BIG hint above.

    Add one more -> no complex formula involved. Think outside the box

    I am sure this is not the only solution. You are welcomed to post your version here for comparison.

    Thanks!

    Don't quite understand, why "Add Point F on side AC such that angle FBC = 20" ?

    Where is the 20 derived from?
