WebJan 9, 2024 · When you use the law of cosines to find some angle θ of a triangle, first you try to get cos θ by itself, and you end up with an equation of the form cos θ = BLAH ( BLAH is just some number). Since θ is the angle of triangle, you know that 0 < θ < 180 ∘, so you get that θ = cos − 1 BLAH. WebSolving similar triangles: same side plays different roles.
