In the diagram below, DE is a chord of the circle that goes through c,d and e. A is the center of the circle. The perpendicular line from centre A intersects DE at B and the circle at C,
DE=100cm BC= 10cm AB=X
I need to calculate the length of AB / x.
Basically i need to calculate the radius of the circle without the diameter or circumference or anything. Do you have any suggestions as to how I would do this?
