Three lines `3x+4y+6=0, sqrt(2) x + sqrt(3) y + 2sqrt(2)=0 and 4x+7y+8=0` are (A) sides of triangle (B) concurrent (C) parallel (D) none of these

sqrt(2)x+sqrt(3)y=0 sqrt(3)x+sqrt(8)y=0

sqrt(2)x+sqrt(3)y=0sqrt(3)x-sqrt(8)y=0

Statement 1: Lines 3x+4y+6=0,sqrt(2)x+sqrt(3)y+2sqrt(2)=0 and 4x+7y+8=0 are concurrent. Statement 2 : If three lines are concurrent then determinant of coefficients should be non-zero.

Statement 1: Lines 3x+4y+6=0,sqrt(2)x+sqrt(3)y+2sqrt(2)=0 and 4x+7y+8=0 are concurrent. Statement 2 : If three lines are concurrent then determinant of coefficients should be non-zero.
