Rotating the phasor creates a sine wave. The amplitude of the phasor is the sine of the angle (Assuming a max amplitude of 1). If the max was 100 the phasor would be 100* sine(theta) etc.

The angular velocity can be measured in degrees and using a sine table the amplitude can be determined. As an example let's look at 45 degrees. Sine is the first column. sine 45 degrees is .7071. Assuming a 100 volt peak the amplitude at 45 degrees would be 100*.7071 = 70.71.

Using the sine chart it would be possible to determine the value of the signal at any angle or conversely to determine the angle at and signal level. Now you can assign values to the waveform and determine the angle using the chart.
