If the slope of one of the lines `2x^(2) + 3xy + lambda y^(2) = 0` is 2 then the angle between the lines is

The slope of one of the lines 2 x^(2)+3 x y+lambda y^(2)=0 is 2, then the angle between the lines is

If the slope of one of the line represented by 2x^(2)+3xy+Ky^(2)=0 is 2 then angle between pair of lines is

If the slope of one of the line represented by 2x^(2)+3xy+ky^(2)=-0 is 2 then angle between pair of lines is

If slope of one of the lines 3x^(2)+4xy+lamday^(2)=0 is thrice slope of the other line then lamda=

The angle between the lines x^(2) + 4xy + y^(2) = 0 is

If the acute angle between the lines ax^(2)+2hxy+by^(2)=0 is congruent to the acute angle between the lines 3x^(2)-7xy+4y^(2)=0 , then

The angle between the lines ay^(2)-(1+lambda^(2)))xy-ax^(2)=0 is same as the angle between the line:

The angle between the lines ay^2-(1+lambda^2)xy-ax^2=0 is same as the angle between the line:

The angle between the lines ay^2-(1+lambda^2)xy-ax^2=0 is same as the angle between the line:
