WebSo the law of cosines tells us that C-squared is equal to A-squared, plus B-squared, minus two A B, times the cosine of theta. And just to remind ourselves what the A, B's, and C's are, C is the side that's opposite the angle theta. So if I … WebThe law of sines establishes the relationship between the sides and angles of an oblique triangle(non-right triangle).
