Answer:

$\huge\underline{ \underline{ \red{your \: \: answer}}}$

Step-by-step explanation:

$sin \frac{ \pi}{3} cos \frac{ \pi}{6} + sin \frac{ \pi}{6}cos \frac{ \pi}{3} \\ \\ we \: know \: that \: \pi = 180 \degree \\ \\ sin \frac{180 \degree}{3} cos \frac{ 180\degree}{6} + sin \frac{ 180\degree}{6}cos \frac{ 180\degree}{3} \\ \\ sin60\degree \: cos 30\degree + sin 30\degree \: cos 60\degree \\ \\ = = > \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{3} }{2} + \frac{1}{2} \times \frac{1}{2} \\ \\ = = > \frac{3}{4} + \frac{1}{4} \\ \\ = = > \frac{4}{4} \\ \\ = = > 1$
