P R (5,0) The figure shows a circle centered at the origin with an angle of measu radians in standard position. The terminal ray of the angle intersects th circle at point P, and point Ralso lies on the circle. The coordinates of are (x, y), and the coordinates of R are (x, y). Which of the followin true about the sine of 0? A sin 0, because it is the ratio of the horizontal displacement of P from the y-axis to the distance between the origin and P B sin = , because it is the ratio of the horizontal displacement of R from the y-axis to the distance between the origin and R. O D sin 0, because it is the ratio of the vertical displacement of R from the x-axis to the distance between the origin and R. sin 0=, because it is the ratio of the vertical displacement of P from the x-axis to the distance between the origin and P.
