You can put this solution on YOUR website! Should the triangle be solved beginning with Law of Sines, or Laws of Cosines. Then solve the triangle and round to the nearest tenth. A=56 degrees, B=38 degrees, a=13.
------------------
Law of Sines:
b/sinB = a/sinA
b/sin(38) = 13/sin(56)
b = sin(38)
b = 9.65408...
-----------------
C = 180 - (56 + 38) = 86 degrees
-----------------
c = sin(86) = 15.6426...
