Law Of Cosines Formula To Find An Angle | Use the law of cosine formula to know Angle of Triangle | Use the examples to learn well and understand
The Law of Cosines is useful for finding:the third side of a triangle when we know two sides and the angle between them (like the example above) the angles of a triangle when we know all three sides (as in the following example)

The meaning of LAW OF COSINES is a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
Since the Law of Cosines is a generalization of the Pythagorean theorem, whenever you can use the Pythagorean theorem, you can also use the Law of Cosines. The Pythagorean theorem is a special case of the Law of Cosines such that when the cosine of an angle is equal to 0, the angle ...
Fig. 3 – Applications of the law of cosines: unknown side and unknown angle. The theorem is used in triangulation, for solving a triangle, i.e., to find (see Figure 3): the third side of a triangle if one knows two sides and the angle between them: ...
The law of cosines is used if there is a need for the third side of any triangle and you have information on the lengths of the other two sides and the angle between them. Also, it is used to get the values of angles in a triangle, if the three sides are known.The...
What is the Law of Cosines? Learn the definition of the law of cosines and see examples of how to use the equation to solve for sides and angles in...
If two sides and the included angle (SAS) of an oblique triangle are known, then none of the three ratios in the Law of Sines is known. Therefore you must first use the law of cosines to find the third side or the side opposite the given angle. Follow the three steps below to solve...
