Choice C is correct. The sine of an angle is equal to the cosine of the angle's complement. This relationship can be expressed by the equation sin x°=(cos)(90°-x°). Therefore, if sin x°=a, then (cos)(90°-x°) must also be equal to a.Choices A and B are incorrect and...

When the sine of y is equal to x: siny=x Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: arcsinx= sin-1(x) =y See:Arcsin function Sine table x (°) x (rad) sin x -90°-π/2-1 ...
In the illustration below, sin(α) = a/c and sin(β) = b/c. From cos(α) = a/c follows that the sine of any angle is always less than or equal to one. The function takes negative values for angles larger than 180°. Since for a right triangle the longest side is the ...
and the opposite side to the angle and hypotenuse. or you can say, the sine of angle theta is equal to the ratio of perpendicular and hypotenuse of a right-angled triangle. the trigonometry ratios sin, cos and tan for an angle are the primary functions. the value of sin 60 degrees and...
