The question is attached

DerKrebs [107]

$cos(A - B) = cos A cos B + sin A sin B$

In this case, A is $\frac{\pi }{3}$ and B is $\frac{\pi }{5}$ , so:

$cos\frac{\pi}{3} cos\frac{\pi}{5} +sin\frac{\pi }{3} sin\frac{\pi }{5} =cos(\frac{\pi}{3} -\frac{\pi}{5} ) = cos\frac{2\pi}{15}$

Hope that helps!
