Question 287603: if you are given two sides of a triangle and an included angle. how do you find the third side? please help if possible. thank you Answer by dabanfield(803) (Show Source):
You can put this solution on YOUR website! The "Law of Cosines" says that for a triangle with sides a, b and c:
c = a^2 + b^2 -2ab*cos(x) where x is the angle between sides a and b (that is the angle opposite side c).
