First we need to find one angle using cosine law, say cos α = [b2 + c2 – a2]/2bc. Then we will find the second angle again using the same law, cos β = [a2 + c2 – b2]/2ac Now the third angle you can simply find using angle sum property of triangle.
WebThe Law of Cosines come in different forms depending on which angle or side you wish to find. One of the missing bits of information about our triangle is side length a. It is important to find this side because with side length a we can use the Law of Sines to easily find the angle measures. Side a "unlocks" the problem. The pertinent LOC is .
