Applying the law of cosines when no triangle exists

Описание к видео Applying the law of cosines when no triangle exists

Learn how to solve for the lengths of the sides and the measures of the angles of a triangle using the law of cosines. The law of cosines is used in determining the lengths of the sides or the measures of the angles of a triangle when no angle measure and the length of the side opposite the angle are both known.

The law of cosines can be used to find the measure of an angle when the length of the three sides of a triangle are known. The law of cosines can be used to find the length of the side of a triangle when the lengths of the other two sides are known and the measure of the opposite angle is known.
