For the answer to the question above asking to f<span>ind the exact value of cos 165 degrees.
The answer to this question is
</span><span>cos 165 = cos (120+45) </span>
<span>= cos120 cos 45 - sin 120 sin 45 </span>
<span>= (-1/2)(sqrt(2)/2) - (sqrt(3)/2)(sqrt(2)/2) </span>
<span>= (-sqrt(2) - sqrt(6))/4
