i think its false...

anonymous · Answer

I leaning towards true..

anonymous · Answer

i think its false becasue that is teh defintion for law of sinces not law of cosines

anonymous · Answer

The law of cosines is c^2 = a^2+ b^2-2ab cos(C), thus allowing you to find an angle of the triangle with only sides

anonymous · Answer

since the law of sines, a/sin A= b/sin B=c/sin C, you would have to know at least on angle to use it to solve for a variable
