Urgent need ~ ~ People's Education Edition Senior High School Mathematics Compulsory 2 Chapter 4 Circle and Equation After-school Exercise Answers.
The position of point c is the intersection of vertical lines l and OA,
The straight line OA is y = 0.5x, and the vertical line of OA is y=-2x+2.5.
At the same time, the vertical lines of L and OA are y=-2x+2.5, and C is (6/5,110).
The standard equation of a circle is (x-6/5)? +(y- 1/ 10)？ =29/20
