: Oblique triangles:
Solve for each triangle.
B=19.3m C=28.7m A=57.0 degrees

This is all the information my book gives and I am not clear on what to do with it? I tried looking at exsamples? Can you help? Thanks. This question is from textbook

Answer by scott8148(6628) (Show Source): You can put this solution on YOUR website!
you can find side a by using the law of cosines ___ a^2 = b^2 + c^2 – 2bc cos A

you can then find angles A and B using the law of sines ___ a/sin(A) = b/sin(B) = c/sin(C)
