Question

Solve question no.10. For take brainliest................. .please.

Answer 1

A(a,b+c),B(B,c+a)& C(c,a+b)
$x1(y2 - y3) + x2(y3 - y1) + x3(y2 - y1) = 0 \\ a(c + a - a - b) + b( a+b - b - c) + c( b+ c - a- c) =0 \\ a(c - b) + b(a - c) + c(b - a) = 0 \\ ac - ab + ab - cb + cb - ac = 0 \\ 0 = 0$
hence all the points are collinear.

Answer 2

above is the solution
hope dis'll help u
