In trigonometry, the Law of sines is a relationship (or proportion) of angles in a non-right triangle. If the sides of a triangle are a, b, and c, and the angles are A, B, and C, then the law of sines states:
where R is the radius of the circumcircle.
[edit] Examples
Given
- A = 300, a = 12, b = 6
-
- 12(sinB) = 3
- 12(sinB) = 3
