Question

Liven the line.
( k x+3 y=1=0 )
( 2 x+y+5=0 ) are bonjugete
with respext to ( x^{2}+y^{2}-2 x-4 y-4=0 )
( triangle 0 )
( (k x+3 y-1)(2 x+y+5)=x^{2}+y^{2}-2 x-4 y-4 )
equating He Coeblivient ob ( x^{2}- )
( Rightarrow quad 2 k=1 )
( k=1 / 2 )

# 60 12. Find the value of k if kr + 3y-1=0, 2x + y +5=0 a x + y2 – 2x - 4y –4=0. with respect to
