I tried a lot of attempts on this problem, but I couldn't get the right answer. (12.06, 5.44, 5.35, 11.47, 18.69, 18.67, 19.56, 27.03 are all incorrect)

 

Find the length BC, to two decimal places.

Angle B  =  180 -  55 -  26  =  99

 

Law of Sines

 

BC /  sin 55   =  10  / sin 99

 

BC =  10sin 55  / sin 99  ≈   8.29
