Question:-
What is the formula of sin A?
Answer:-
- The opposite side is opposite to the angle to be determined.. In any right angled triangle, for any angle: The Sine of the Angle(sin A) = the length of the opposite side / the length of the hypotenuse. The Cosine of the Angle(cos A) = the length of the adjacent side / the length of the hypotenuse.
