WebThe 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. Webrecall the law of cosines, 𝑎 = 𝑏 + 𝑐 − 2 𝑏 𝑐 𝐴 c o s, recognize how the law of cosines can be applied to a triangle to determine an unknown side length (given a diagram or otherwise), recognize how the law of cosines can be applied to a triangle to determine an unknown angle measure (given a diagram or otherwise).
