👉 Learn how to solve for the length of the sides and the measures of the angles of a triangle using the law of sines. The law of sines is used in determining the length of the opposite side to a known angle measure or the measure of the opposite angle to a known side length of a triangle. 

The law of sines is used when the length of two sides of a triangle is known and the measure of one of the angles opposite a known side length of the triangle is also known. The law of sines can also be used when the measures of two angles of a triangle are known and the length of one of the sides opposite a known angle measure of the triangle is also known.
