C= 27 degrees 50 minutes, c= 349 m, b=428 m

The second one says

A = 104 degrees, a= .69cm, b=.91 cm

Thanks a lot for the help. These are the last two I need to do.

Sin A/a

Use the law of sines

sin A/a = sin B/b = sin C/c

That and the fact that all angles must add up to 180 degrees lets you solve for all unknowns.
