side C=14

side B=4

angle c=145 degrees

i got

angle b= 9.4

angle a=25.6

side A=10.4

but i didn't know if it was correct

**Damon**, Sunday, January 23, 2011 at 5:05pmsin B/b = sin C/c

sin B = (4/14) sin 145

sin B = .1639

B = 9.42

A = 180 - B - C = 180 - 9.42 - 145 = 25.58

so you have the right idea

Angles are usually upper case, sides lower case.
