Answer:

#cos(300^@)=1/2#

Explanation:

Imagine the unit circle:

www.mathsisfun.com

We know that #300^@# is in the fourth quadrant, where cosine is positive.

#300^@# has a reference angle of #60^@#, since it is #60^@# away from the #x#-axis.

Since #cos(60^@)=1/2#, we know that #cos(300^@)=1/2# as well since #cos(theta)>0# in the fourth quadrant.
