A = 23°, B = 55°, b = 9

A = 18°, a = 25, b = 18

C = 180 - 78 = 102 degrees

a = sinA* (b/SinB) = 4.293

c = sinC*(b/sinB) = 10.75

In the second case

sin B = b* (sinA/a) = 0.2225

B = 12.9 or 167.1 degrees

The latter value for B is not possible because the total number of degrees in the triangle would be too high.

C = 149.1 degrees

c = sinC*(a/sinA) = 41.55
