The law of sines can be used to compute the remaining sides of a triangle when two angles and a side are known a technique known as triangulation It can also be used when two sides and one of the non enclosed angles are known The Law of Sines can be used to solve for the sides and angles of an oblique triangle when the following measurements are known Two angles and one side AAS angle angle side or ASA angle side angle
If you have A sin a B sin b you can just solve for the angle using Algebra A B sin a sin b A sin b B sin a a arcsin A sin b B The Law of Sines just tells us that the ratio between the sine of an angle and the side opposite to it is going to be constant for any of the angles in a triangle So for example for this triangle right over here This is a 30 degree angle This is a 45 degree angle They have to add up to 180

The Law of Sines is written formally as where A is the angle opposite side a B is the angle opposite side b and C is the angle opposite side c What is it used for A triangle has three sides and three angles The law of sines also known as the sine rule states that the ratio of side length to the sine of the opposite angle is the same for all sides in a triangle
Review the law of sines and the law of cosines and use them to solve problems with any triangle Law of sines a sin b sin c sin The Sine Rule also known as the law of sines is exceptionally helpful when it comes to investigating the properties of a triangle While the three trigonometric ratios sine cosine and tangent can help you a lot with right angled triangles the Sine Rule will even work for scalene triangles
