➡Here as follows
Let the Second circle equation:--
x² + y² + 2gx + 2fy = 0
▶ So x² + y² 2gx + 2fy = 0 lies equal roots
means, there roots collab with the line
f + g = 0
↪ Equation of common chord we know as
▶ 2(g - 3)x + 2(-g -4)y + 7 = 0
▶(-6x -8y +7 ) + g (2x -2y) =0
By multiply it further, then
▶ It passes through intersection point of
-6x -8y +7=0 & 2x -2y =0
Cos60° = √(h+1)2 + (k -1)²/2
so there ,
by matching the options
it comes to (c) 1/2,1/2
=>Hence Solved!!
