$\sf{we \: know : } \\ \\ \purple{ \sf{sin45 \degree = \frac{1}{ \sqrt{2} } }} \\ \\ \purple{\sf{cos45 \degree = \frac{1}{ \sqrt{2} } }} \\ \\ \purple{\sf{sin60 \degree = \frac{ \sqrt{3} }{2} }}$

$\sf{sin45 \degree.cos45 \degree + \sqrt{3}sin60 \degree } \\ \\ \sf{ = \frac{1}{ \sqrt{2} } \times \frac{1}{ \sqrt{2} } + \sqrt{3}( \frac{ \sqrt{3} }{2} )} \\ \\ \\ \sf{ = \frac{1}{( \sqrt{2} ) {}^{2} } + \frac{( \sqrt{3} ) {}^{2} }{2} } \\ \\ \sf{ = \frac{1}{2} + \frac{3}{2} } \\ \\ \sf{ = \frac{1 + 3}{2} } \\ \sf{ = \frac{4}{2} } \\ \\ \sf{ \underline{ \underline{ \bold{ = 2}}}}$
