WebOne way I help remember the Law of Cosines is that the variable on the left side (for example, \({{a}^{2}}\) ) is the same as the angle variable (for example \(\cos A\)), and the … WebThe law of cosines can be used when we have the following situations: • We want to find the length of one side and we know the lengths of two sides and their intermediate angle. • We want to find the measure of any angle and we know the lengths of the three sides of the triangle. To use the law of cosines, we always use the angle between the two known sides.
