Answer:
sin θ = Perpendicular / Hypotenuse
Explanation:
The sine of an angle of a right-angled triangle is the ratio of its perpendicular (that is opposite to the angle) to the hypotenuse. The sin formula is given as: sin θ = Perpendicular / Hypotenuse. sin(θ + 2nπ) = sin θ for every θ
Cosine theta equals x, sine theta equals y and tangent theta equals y over x,
Cos0=sin (90 degrees -0)
Sin0= cos ( 90 degrees -0)
