The law of cosines allows us to find angle or side length measurements for triangles other than right triangles The third side in the example given would ONLY 15 if the angle between the two sides was 90 degrees In the example in the video the angle between the two sides is NOT 90 degrees it s 87 As such that opposite side length isn Law of Cosines a2 b2 c2 2bc cos a b2 a2 c2 2ac cos b c2 a2 b2 2ab cos c Case 1 SSS a 21 2 ft b 24 6 ft and c 12 ft since you don t know any angle just pick 1 to find first After you find one angle you can switch back to law of sines or use the cosine again Case 2 SAS C 134o a 20 and b 8 Hint
