Answer 2

Question :- Express 85° + cosec 85° in terms of trignomentric ratios of angles between 0° and 45°

Answer:

cos 5° + sec 5°

Step-by-step explanation:

sin 85° + cosec 85°

sin (90° - 5°) + cosec ( 90° - 5°)

= cos 5° + sec 5°

Trignomentry identity used:-

sin (90°- A) = cos A

cosec (90° - A) = sin A

Therefore, the required trignomentric ratio is cos 5° + sec 5°
