Answer:The answer to your question is cos 30° = \frac{ \sqrt{3} }{2}
Step-by-step explanation:
In this exercise we are going to do calculations on the angle of the cosine function, so we have as an answer:
[tex]cos 30 = \frac{ \sqrt{3} }{2}[/tex]
So we have to remember about the cosine angles, that is
[tex]cos 30 = \frac{ \sqrt{2} }{2}\\cos 45 = \frac{ \sqrt{3} }{2}\\cos 60 = \frac{ {1} }{2}[/tex]
