Law of Cosines Calculator Description The law of cosines , otherwise known as the cosine formula or cosine rule, gives a formula that relates the lengths of the sides of a triangle to the cosine of one of its angles. where is the angle between the sides.
.944 with the aid of a calculator.Therefore, on inspecting the Table for the angle whose sine is closest to .944,Angle F 71°. And therefore,Angle E = 180° − (71° + 60°) = 180° − 131° = 49°.And so using the Laws of Sines and Cosines, we have completely solved the...

Law of Cosines If △ABC has side lengths a, b, and c that are opposite angles A, B, and C, then Law of Cosines You can use the Law of Cosines to solve a triangle if you know the measure of two sides and the included angle (SAS) or the measure of all three sides. ...
The Law of Sines One method for solving for a missing length or angle of a triangle is by using the law of sines. The law of sines, unlike the law of cosines, uses proportions to solve for missing lengths. The ratio of the sine of an angle to the side opposite it is equal for ...
