Use the Law of Cosines to determine the indicated side x. (Assume b = 14 and c = 18. Round your answer to one decimal place.) C 19 b 108 x B Step 1 The Law of Cosines states that for the triangle ABC with sides a, b, and c, cos(C). 2ab In the given triangle, you know sides b and c and angle A, and need to find a. So you can rewrite this formula Step 2 a = c+1 (b 4)-( cos(A). x2bc Substitute known values into the alternate form of the Law of Cosines. Round your answer to three decimal places. ) - (2ab a = c + b a = 182 + 14 )-2 14. = 324+ 196 28 cos(A) 18 cos(108) x) cos(108)
