If the bisector of the angles of the lines represented by 3x2−4xy+5y2=0 and 5x2+4xy+3y2=0 are same, then the angle made by the lines represented by first with the second, is

If the bisector of the angles of the lines represented by 3x2−4xy+5y

1.	If the bisector of the angles of the lines represented by 3x2−4xy+5y2=0 and 5x2+4xy+3y2=0 are same, then the angle made by the lines represented by first with the second, is
Answer» If the bisector of the angles of the lines represented by $3 x^{2} - 4 x y + 5 y^{2} = 0$ and $5 x^{2} + 4 x y + 3 y^{2} = 0$ are same, then the angle made by the lines represented by first with the second, is
