Circle

Circle touch two parallel lines p and q; and its center lies on a line a, which is secant of lines p and q.

Write the equation of circle and determine the coordinates of the center and radius.

p: x-10 = 0
q: -x-19 = 0
a: 9x-4y+5 = 0


Result

xS =  -4.5
yS =  -8.88
r =  NAN

Solution:

Solution in text x__S =
Solution in text y__S =
Solution in text r =

Pythagorean theorem is the base for the right triangle calculator. Looking for help with calculating roots of a quadratic equation? Do you have a system of equations and looking for calculator system of linear equations? For Basic calculations in analytic geometry is helpful line slope calculator. From coordinates of two points in the plane it calculate slope, normal and parametric line equation(s), slope, directional angle, direction vector, the length of segment, intersections the coordinate axes etc.
