Question 490320: A triangle has sides a=4 and b=6 and C= 60 degrees. Find the length of c ( I need help with my homework problem) Answer by John10(297) (Show Source):
You can put this solution on YOUR website! Hint: apply the Cosine rule:
C^2 = A^2 + B^2 - 2AB*Cos C
Substitute A = 4 and B = 6, Angle C = 60 degrees.
