1. Law of Sines
We need the law of sines because no all triangles will end up being right triangles and we need to know how to solve for all the missing parts of the triangle. If we thing of what is around us we will not be able to know exactly what everything is unless we know some kind of rule or equation to help us figure this out.
4. Area of an Oblique triangle
This equation is related to the equation of finding the area of a triangle because that is what we are using. The only thing that we are changing is how the height is being represented. instead of writing h we are using asinC and that is still equivalent to the height.
