Puzzle tiem.

A triangle has sides a,b,c and corresponding angles A,B,C (angle A is opposite side a, etc.).

You are given that c = 12, a/b = 9/5, and A - B = 2C.

Find the sides and angles of the triangle.

A + B + C = pi  
A - B - 2C = 0
sinA - 9/5sinB = 0  *from law of sines

3 eq's and 3 unknowns

plug shit in...


a=18
b=10
c=12

A=~1.910633236
B=~0.5512856
C=~0.679673818

too lazy to find exact values for A, B and C
