1. Point E (0, -28.262) is the center for Arc{AJB} with Radius 424.768. So the equation for Arc{AJB} is:

*x² + ( y + 28.262 )² = 424.768² *

or

*x² + ( y + 28.262 )² = 180427.8538 *

2. Point H (75.509, 0) is the center for Arc{AID} with Radius 344.143. So the equation for Arc{AID} is:

*( x - 75.509)² + y² = (344.143)² *

or

*( x - 75.509)² + y² = 118434.4045 *

3. Point A is the intersection of Arc{AJB} and Arc{AID} and Points E, H and A are collinear. This implies that the radial segment of Arc{AJB} and the radial segment of Arc{AID} share Segment{HA} in common.

4. Therefore, the equation of Line Segment{EHA} , which is determined by Point E (0, -28.262) and
Point H (75.509, 0) would be helpful in finding coordinates for Point A.
