The equation of the circle whose centre is at point o' is x 2+32 x + y 2 - 24 y = 0 the coordinates of point a are (-34.794m. 18.840m). and those of point b are (-7.548m,30.126m). the tangents to the circle : line ac at a. and line bc at b intersect at point c. find the coordinates of point c to a precision of 1mm.
