  2. LAW OF COSINES

  3. Examplea=21 b=16.7 c=10.3 Take the equation and put the values into the variables Then solve for all the squares and the multiplication

  4. Then add a and b together and subtract the value from the both sides of the equation Next divide both sides by the value in front of the Cosine Take the Inverse of Cosine and the answer will be the degree of angle A
