Question

solve this
1/4[root 3 cos 23 degree-sin 23 degree] is equal to​

Answer 1

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

Answer 2

Answer:

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
