sin rule for triangles and solving trignometric functions

Solve the triangle. Round lengths to the nearest tenth and degrees.

1. B = 43, C = 107, B = 14
2. C = 110, a = 5, b = 11
3. B = 54, C = 112, b = 35

Find the solution

2 cos(theta) + 1 = 0

===============================================================================

A = 29.9 a = 10.2
B = 43 b = 14
C = 107 c = 19.6
-------------------------------

a/sin A = b/sinB=c/sin C
a/sin A = 14/sin43=c/sin 107

c = ...
