Question

Sin85° = (90°-5°) =​

Answer 1

Ответ:

sin(85°)=sin(90°-5°)=cos(5°)

Answer 2

It seems like you're trying to express the value of sin(85°) by using a trigonometric identity. However, the identity you've written, sin(85°) = (90° - 5°), is not accurate.

The value of sin(85°) cannot be simplified using that particular identity. You would typically use a calculator or a trigonometric table to find the approximate value of sin(85°), which is approximately 0.996194698.

If you have a specific trigonometric identity in mind that you'd like to use to simplify sin(85°), please provide more details, and I'd be happy to assist you further!
