) sin(A - B) = sin A cos B-cos A sin B. -. -. 3.) cos(A+B) : = cos A cos B - sin A sin B. 4.) cos(A – B) = cos A cos B + sin A sin B. You MUST memorize the ... ANSWER: m∠B cannot be found. NO such triangle exists. In relation to triangles, sin B must be < +1 for angle B to exist. It states that a/sin A = b/sin B = c/sin C, where a, b, and c are the triangle's lengths and A, B, and C are the triangle's angles. This formula may be ...
