O 6.50 O 8.73 4.02 Question 8 (10 points) Consider a triangle where a = 5, b = 10, and C = 520 (Note that the triangle shown is not to scale.) Use the Law of Cosines to find c. Round your answer to two decimal places. Be careful if you round off in your intermediate calculations, make sure that you take enough decimal places. Your Answer: Question 9 (10 points) If the length a = 40, find the length x. Express your answer to two decimal places. 26

Solution

C=180-A-B=150 degree

Using sine law

sinA/a=sinC/c

sin13/5= sin 150/c

c= 5 sin 150/sin 13= 11.11
