    1366(tan(12'50'')) '=degree and ''=minute for this one :)

    319.554 is what the calculator spits out :) that is if 79/6 is a good number. 12 and 50/60 = 12 5/6 = (72+5)/6 = 77/6 gotta recalc it :)

    [30(60)+5]/60 is going to be the number for my degrees.. tan(n) = 1065/x x = 1065/tan(n)...
