Question

what is the formula of sin a​

Answer 1

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.

Answer 2

Step-by-step explanation:

Sine, Cosine and Tangent

Sine Function: sin(θ) = Opposite / Hypotenuse

Cosine Function:. cos(θ) = Adjacent / Hypotenuse

Tangent Function: tan(θ) = Opposite / Adjacent
