  1. Use the Sine law to solve for the length of the indicated side.

I get too:

Sin 108/12.9 = sin 24/b

0.951056516.../12.9 = .406736643076/b

 

12.9/0.951056516 = b/.40673664307

 

12.9/0.951... = 13.563...

 

13.563 *.4067... = 5.516... 

 

5.52 IS RIGHT!!!!! :)

12.9/sin 108   =  b/sin24

 

sin 24  12.9/sin108 = b = 5.52 m

b / sin 24 =  12.9 / sin 108      multiply both sides by  sin 24

 

b =  12.9 sin 24  / sin 108 ≈   5.52 m
