Answer 1

Circumcenter,,,, ufff!

You must know the trick to find circumcentre.

Circumcentre-

Let the coordinates of the circumcentre of the triangle be (x, y).
Circumcentre of a triangle is equidistant from each of the vertices.

Distance between (12,8) and (x,y)= Distance between (6,0) and (x,y)

Apply distance formula and solve. You will get the equation 3x+4y=43

Now do the same with (-2,6) and (6,0).
You will get the equation 4x-3y= -1

Solve the equation and you will get x=5 ---------1
