161 1127 Given the geometric sequence: 23 18 324 Find an explicit formula for an: Find an :Assume Zo is opposite side a, ZB is opposite side b, and Zy is opposite side c. Solve triangle ABC if ZA = o = 33.8', b = 9.2 m, and c = 13.3 m. Using the Law of Cosines, m. Your answer should accurate to 2 decimal places. Using the Law of Cosines again, COS/ B = COS B Your answer should accurate to 5 decimal places. Thus, B ~ Your answer should accurate to 2 decimal places. cos/C = cosy = Your answer should accurate to 5 decimal places. Thus, Y Your answer should accurate to 2 decimal places. Check by seeing if the total of the three angles is 180.Solve triangle ABC if 111 = 317.9\Find the first term and the common difference ef the arithmetic sequence wh05e 9'11 term i5 6 and 14':'1 term is 21.
