Question

find the equation of the circumcircle of a triangle whose sides are given by the equations 2x + y - 3 = 0, x - 2y + 1 = 0 and 3x - y - 7 = 0​

Answer 1

Answer:

triangle whose sides are given by the equations 2x + y - 3 = 0, x - 2y + 1 = 0 and 3x - y - 7 = 0

Let the eq.of cir cle is:-

x^2+y^2+2gx+2fy+c=0………………….(4)

The circle passes through point (1,1), (2,-1) and (3,2).

Equation of required circle is,

x^(2)+y^(2)-5x-y+4=0
