143 Cos 23° - Sin 23° ,

So.....

⇒12 × 123 Cos 23° - Sin 23°

⇒1232 Cos 23° - 12Sin 23°

⇒12Sin 60° Cos 23° - Cos 60°Sin 23°              

⭕️ (  We know Sin 60° = 32  and Cos 60° = 12 )

⇒12Sin  60° - 23°                                             

⭕️ (  We know Sin  A - B  =  Sin A Cos B  - Cos A Sin B )

⇒12Sin 37°

⇒12× 0.6018                                                             

⭕️(  we know Sin 37° =0.6018 )

⇒0.3009
