WebCosine Formulas Using Law of Cosines The law of cosines is used to find the missing sides/angles in a non-right angled triangle. Consider a triangle ABC in which AB = c, BC = a, and CA = b. The cosine formulas using the law of cosines are, cos A = (b 2 + c 2 - a 2) / (2bc) cos B = (c 2 + a 2 - b 2) / (2ac) cos C = (a 2 + b 2 - c 2) / (2ab) WebRemember: When we use the words 'opposite' and 'adjacent,' we always have to have a specific angle in mind.
