If `3x+4y=12sqrt(2)` is a tangent to the ellipse `(x^(2))/(a^(2))+(y^(2))/(9)=1` for some `a in R` ,then the distance between the foci of the ellipse is

the distance between the foci of the ellipse 5x^(2)+9y^(2)=45, is

The foci of the ellipse (x^(2))/(4) +(y^(2))/(25) = 1 are :

if the line x- 2y = 12 is tangent to the ellipse (x^(2))/(b^(2))+(y^(2))/(b^(2))=1 at the point (3,(-9)/(2)) then the length of the latusrectum of the ellipse is

3x + 4y = 12 sqrt2 is the tangent to the ellipse x^2/a^2 + y^2/9 = 1 then the distance between focii of ellipse is-

The distnce between the foci of the ellipse 3x ^(2) + 4y ^(2) =48 is

Foci of ellipse ((x-1)^(2))/(4)+((y-2)^(2))/(9)=1 is/are

The straight line x+y=a will be a tangent to the ellipse (x^(2))/(9)+(y^(2))/(16)=1 if a=

If the distance between the parallel tangents to the ellipse (x^(2))/(4)+(y^(2))/(1)=1 is 3 units then the slope is

Equations of tangents to the ellipse (x^(2))/(9)+(y^(2))/(4)=1 which are perpendicular to the line 3x+4y=7, are
