1.	In order to apply the law of cosines to find the length of the side of a triangle, it is enough to know which of the following ?the area of a triangle ? The measure of an angle and the length of the side opposite that angle ? the lengths of the two triangle sides and the measure of the angle between them ?
Answer» In order to apply the law of cosines to find the length of the side of a triangle, it is enough to know which of the following ? the area of a triangle ? The measure of an angle and the length of the side opposite that angle ? the lengths of the two triangle sides and the measure of the angle between them ? Solution: In order to apply the law of cosines to find the length of the side of a triangle, we need to know the length of two sides of the triangle and the measure of the angle. In trigonometry, the law of cosines relates the lengths of the sides of a triangle to the cosine of one of its angles.
