For this case, we must indicate the value of Cosine (60) according to the triangle shown.
By definition we have to:
[tex]cosine (x) = \frac {leg \ adjacent \ to \ angle \ x} {Hypotenuse}[/tex]
So, we have:
[tex]cosine (60) = \frac {leg\ adjacent \ to \ angle \ 60} {Hypotenuse}\\cosine (60) = \frac {1} {2}[/tex]
So, the cosine of 60 is[tex]\frac {1} {2}[/tex]
Answer:
[tex]\frac {1} {2}[/tex]
Option D
