The "Law of Sines" can be expressed as $$ {a \over sin A } = {b \over sin B } = {c \over sin C } \tag{1}$$ where a, b and c = length of sides in triangle (m, ft ...) A, B and C = angles in the triangle (degrees) Law of Sines Calculator a (m, ft ......
If you know other properties of the triangle, you can solve the remaining sides and angles using the Law of Cosines. How to Use the Law of SinesThe Law of Sines is particularly useful when you know either: Two angles and one side (aka AAS): If you know two angles and the length of...

If we are given two sides and an included angle (SAS) or three sides (SSS) we will use the Law of Cosines to solve the triangle. Law of Sines: Given Two Angles And One Side We will first consider the situation when we are given 2 angles and one side of a triangle. Example: ...
The meaning of LAW OF COSINES is a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.
