So I have some circles that look a kind like this:
I'm given the radius of the circle with center point $A$ which is also the distance $AB$, the distance $AB$ between the two center points on the x axis (they share same $y$ values for the centers), and the distance $CD$ which is the height of the shape created by the intersection.
We can also assume that despite my drawing the circle are perfect circles.
I'm looking for a way to find the distance $BD$ which is also the radius of the circle centered at the point $B$.
Thanks in advance for any help.
