Answer:
cos 30 = √3 /2
cos 60 = 1/2
Explanation:
The cosine ratio for 30 degrres gives
[tex]\cos 30=\frac{4\sqrt[]{3}}{8}[/tex]
which simplifies to give
[tex]\cos 30=\frac{\sqrt[]{3}}{2}[/tex]
The cosine ratio for 60 degrees gives
[tex]\cos 60=\frac{4}{8}[/tex]
simplifying the right-hand side gives
[tex]\cos 60=\frac{1}{2}[/tex]
which is our answer!
Hence, the correct answer choices are
cos 30 = √3 /2
cos 60 = 1/2
