Question

how do i solve this???​

Answer 1

The answer is 1

Step-by-step explanation: The explantion is simple

sin 5°· cos 85°+ cos 5°· sin 85° can be written as

sin 5°· cos(90-5°)+ cos 5°· sin (90-5°)

= sin 5°. sin 5° + cos 5°· cos 5°

= sin²5° + cos²5°=1

Answer 2

Answer:

1

Step-by-step explanation:

sin5.cos85 + cos5.sin85

= sin (90-85).cos85+ cos(90-85)+sin85

= cos85.cos85+ sin 85.sin 85

= cos²85 + sin² 85

( cos² ¤ + sin² ¤ = 1)

hence the answer is

hence the answer is 1
