law of cosines missing side length Use this law of cosines calculator to determine the third side of a triangle knowing two sides and the angle between them or to find the angles given all three sides
The law of cosines is used to find the missing side of a triangle when its two sides and the included angle is given There are three laws of cosines and we choose one of them to solve our problems depending on the The law of cosines or cosine rule is a formula that can be used to calculate a missing side or missing angle in a triangle To apply the law of cosines you need to know the correct

The cosine rule also known as the law of cosines relates all 3 sides of a triangle with an angle of a triangle It is most useful for solving for missing information in a triangle For example if all three sides of the triangle are Use the Law of Cosines first to calculate the largest angle then use the Law of Sines to find another angle and finally use angles of a triangle add to 180 to find the last angle
Use the Cosine Rule to find the missing side When we have two sides and the included angle the law of cosines allows us to find the third side Applying the cosine rule for side b We are given the lengths of two sides and the measure of an included angle so we may apply the Law of Cosines to find the length of the missing side
