Question

The law of cosines is used to find the measures of a triangle when only the three sides are known, because the law of sines requires at least one angle measure.
A.
True
B.
False

Answer 1

i think its false...

Answer 2

I leaning towards true..

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

oh
