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.

Use The Law of Cosines (angle version) to find angle C : cos C = (a2 + b2 − c2 )/2ab = (82 + 62 − 72 )/2×8×6 = (64 + 36 − 49)/96 = 51/96 = 0.53125 C = cos−1 (0.53125) = 57.9° to one decimal place Versions for a, b and c Also, we can rewrite the c2 = a2 + b2 − 2ab cos (C) formula into a2= and b2= form. Here are all three:
