The Law of Cosines is
, where c is the unknown side length of a triangle, a and b are the remaining two side lengths, and C is the angle opposite to side c. To answer this question just plug in the known values:
![m^2=21^2+12^2-2(21)(12) cos(62)](https://tex.z-dn.net/?f=m%5E2%3D21%5E2%2B12%5E2-2%2821%29%2812%29%20cos%2862%29)
Simplify:
![m^2=441+144-504 cos(62)](https://tex.z-dn.net/?f=m%5E2%3D441%2B144-504%20cos%2862%29)
![m^2=585-504 cos(62)](https://tex.z-dn.net/?f=m%5E2%3D585-504%20cos%2862%29)
![m=\sqrt{585-504cos(62)}](https://tex.z-dn.net/?f=m%3D%5Csqrt%7B585-504cos%2862%29%7D)
m≈18.665...
When rounded to the nearest tenth, m=18.7
