If the line x-2y=12 is tangent to the ellipse x^2/a^2+y^2/b^2 =1 at the point (3,-9/2) then the length of latus rectum be=? If the line x-2y=12 is tangent to the ellipse x^2/a^2+y^2/b^2 =1 at the point (3,-9/2) then the length of latus rectum be=?
Dear StudentTangent at(3,−9/2)3x/a^2− 9y/2b^2=1on Comparing this with given equation of tangenti.e x−2y=123/a^2=9/4b^2=1/12We geta=6andb=3√3length of latus rectum=2b^2/a =9Thanks
