There is only 1 remaining side

We have 2 sides and an included angle, we use the Law of Cosines to solve the third side:

c^2 = a^2 + b^2 - 2ab * cos (C)

c^2 =.5^2 +.333333333 ... ^2 - 2 *.5 *.3333333 ... * cos (95)

c^2 =.25 +.1111111111111111 ... - 2*.5*.3333333333 ... * - 0.087156

c^2 = 0.3611111111 + 0.029052

c^2 = 0.3901631111

c = 0.6246303796
