If the pair of lines `ax^2+2(a+b)xy+by^2=0` lie along diameters of a circle and divide the circle into four sectors such that the area of one of the sectors is thrice the area of another sector then

If the pair of lines ax^2 +2 (a + b) xy + by^2 =0 lie along diameters of a circle and divide the circle into four sectors such that the area of one of the sectors is thrice the area of another sectors, then:

If the pair of lines ax^(2)+2(a+b)xy+by^(2)=0 lie along diameters of a circle and divide the circle into four setors such that the area of one of the sectors is thrice the area of another sector then
