Sin PI/5 cos 3PI/10 + cos PI/5 sin 3PI/10? The Correct Answer and Explanation is : he expression ( \sin\left(\frac{\pi}{5}\right) \cos\left(\frac{3\pi}{10}\right) + \cos\left(\frac{\pi}{5}\right) \sin\left(\frac{3\pi}{10}\right) ) can be simplified using the sine addition formula, which states:[ \sin(A + B) = \sin(A)\cos(B) + \cos(A)\sin(B) ]y comparing this formula to the given expression, we can identify ( A
