The law of sines can be used when solving any triangle, including non-right triangles. The law can be applied if any side and its opposite angle are both known. How is Law of Sines explained? The law of sines is an identity that relates the side-lengths and angles of any triangle. Th...
The law of sines formula is used for relating the lengths of the sides of a triangle to the sines of consecutive angles. It is the ratio of the length of the side of the triangle to the sine of the angle thus formed between the other two remaining sides. The law of sines formula is...

It took quite a few steps, so it is easier to use the "direct" formula (which is just a rearrangement of the c2 = a2 + b2 − 2ab cos(C) formula). It can be in either of these forms:cos(C) = a2 + b2 − c2 2ab ...
