Angle between the lines 2x^(2)-7xy +3y^(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

If theta is the measure of acute angle between the pair of line repseented by ax^(2) + 2hxy + by^(2) = 0 , then prove that tan theta = |(2sqrt(h^(2) - ab))/(a+b)|,a + b ne 0 Hence find the acture angle between the lines x^(2) - 4xy + y^(2) = 0
