Assume A is opposite side a, B is opposite side b, and C is opposite side c. Use the Law of Cosines to colve for angle A of the oblique triangle with the given side lengths: a = 11,6 = 20, c= 27. Round your answer to the nearest tenth.

Given a=37, b=32 and c=25, use the law of cosines to find angle y.
