@Data_LG2 do you know how to solve this?

Answer 7

\(\LARGE \frac{\pi}{6}=30°\), so

\(\LARGE {cos\ \theta = \frac{adjacent}{hypotenuse}\\cos\ 30°=\frac{1}{2}}\)

Answer 8

the end result is still in radical form though in the numerator

Answer 9

the adjacent and the hypotenuse are already a whole number so you don't have to rationalize anything.
