I have a circle, diameter and radius unknown. It has a chord running through the center (point "O") and the end points are on the circle. Lets call this chord "SR" This chord SR bisects another chord "TU" and TU has midpoint "K". The only other information I have is that arc angle "TR" formed by point "T" from chord TU and point "R" from chord SR equals 150 degrees; I also have segment "OK" (midpoint "K" of chord TU, and center of circle "O") equals 8*sqrt3. Thats all. I need to figure out what "SR equals
This shows how to figure out the length of a chord of a circle.
