SOLUTION:-

L.H.S

sin150° cos120°+ cos330°sin600°

 =  &gt; sin(180 - 30) \degree \: cos(180 - 60) \degree \:  + cos(360 - 30) \degree \: sin(2 \times 360 - 60) \degree    \\ \\  =  &gt; sin30 \degree( - cos60 \degree) + cos30 \degree( - sin60 \degree)  \\ \\  =  &gt;  \frac{1}{2} ( -  \frac{1}{2} ) +   \frac{ \sqrt{3} }{2} ( \frac{ -  \sqrt{3} }{2} )  \\   \\  =  &gt; -   \frac{1}{4}  -  \frac{3}{4}  \\  \\  =  &gt;  \frac{ - 1 - 3}{4}  =   - \frac{4}{4}  \\  \\  =  &gt;  - 1. =  &gt; </strong><strong>R</strong><strong>.</strong><strong>H</strong><strong>.</strong><strong>S</strong><strong>
