WebWhat is the formula for the law of cosines? The formula for the law of cosines is an equation that relates the lengths of two sides of a triangle to the angle between the two sides. The formula for the law of cosines is: { {a}^2}= { {b}^2}+ { {c}^2}-2bc\cos (\alpha) a2 = b2 + c2 −2bccos(α) WebFACTS to remember about Law of Sines and SSA triangles: 1. In a triangle, the sum of the measures of the interior angles is 180º. 2. No triangle can have two obtuse angles. 3. The hypotenuse is always the longest side in a right triangle. So, when working in a triangle with , sin A must be less that +1 (and greater than -1).
