How to get the equation of a geometric relation?

I am trying to find the relationship between the angle (Neck-Shoulder-Thumb) and [Neck-Thumb] distance.

Is there any way I can find the relation directly calculated by GeoGebra?

The question is:

(as seen in the attached image)

The Thumb is a point on the circle with a radius of 62cm, with the center point Shoulder.

The distance between Neck (0,0) and Shoulder (0,-20) is constant and 20cm.

What is the relationship between (neck-shoulder-thumb) angle and [neck-thumb] distance?

Your help is much appreciated...
