Question

find the value of \\(\frac{\cos 45^{\circ}}{3}\\).\
\\(\bigcirc\\) 0.2356\
\\(\bigcirc\\) 0.45\
\\(\bigcirc\\) 0.6\
\\(\bigcirc\\) 0.285

Explanation:

Step1: Recall the value of $\cos 45^\circ$

We know that $\cos 45^\circ=\frac{\sqrt{2}}{2}\approx\frac{1.4142}{2} = 0.7071$.

Step2: Divide by 3

Now, we calculate $\frac{\cos 45^\circ}{3}=\frac{0.7071}{3}\approx0.2357$.

Answer:

0.2356 (closest to the calculated value)
