27. The circumcentre of the triangle with vertices (4, 0),(O, O) and (O, 6) is.IS

Answer»

let A (4,0) be (x1,y1) and B (0,0) (x2,y2) and C(0,6) (x3,y3)

find circumcentre (x,y)

by centroid formula

x=x1+x2+x3/3 and y=y1+y2+y3/3x=4+0+0/3 and y=0+0+6/3x=4/3 and y=6/3therefore, circumcentre (x,y) is (4/3,2)
