Which of the following best explains the value of Sine pi/3 on the unit circle below? a. sine pi/3 = opposite/hypotenuse = opposite/1 = opposite The length opposite the angle is the vertical distance from the x-axis on the graph. b. sine pi/3 = adjacent/hypotenuse = adjacent/1 = adjacent The length adjacent to the angle is the vertical distance from the x-axis on the graph. c. sine pi/3 = opposite/hypotenuse = opposite/1 = opposite The length opposite the angle is the horizontal distance from the y-axis on the graph. d. sine pi/3 = adjacent/hypotenuse = adjacent/1 = adjacent The length adjacent to the angle is the horizontal distance from the y-axis on the graph.
