Determine whether the Law of Sines or the Law of Cosines is needed to solve the triangle. Then solve the triangle. Round your answer to two decimal places. a= 19, b= 21. C = 75° = O Law of Sines: A = 75°, B = 48.770, = 21 O Law of Sines; A = 48.77°, B = 75°, c = 21 Law of Sines: No solution Law of Cosines: A = 48.77°, B = 56.23° c = 24.40
