What are the three situations when you can use the law of sines.
1 you are given a triangle with two angles and the included side.
2 you are given a triangle with all three sides.
3 you are given a triangle with two sides and a non-included angle.
4 you are given a triangle all three angles.
5 you are given a triangle with two angles and a non-included side.

Answer with explanation:

Law of Sines

If the triangle has side length, a , b and c and Angles are A, B and C , then Sine law can be written as

1. You are given a triangle with two angles and the included side.

Find the measure of third Angle, then using sine law find the length of other sides.

3.You are given a triangle with two sides and a non-included angle.

  First evaluate , second angle which is in front of corresponding side and then third angle and other side.

5.You are given a triangle with two angles and a non-included side.

Calculate the third Angle using angle sum property and other sides using sine law.
