If two points `M` and `N` on the hyperbola `x^2/5-y^2/9=45` (whose centre is O), be such that `OM` is perpendicular to `ON` then the value of `(OM^2+ ON^2)/(OM^2+ON^2)` is equal to3) 2

If two points M and N on the hyperbola (x^(2))/(5)-(y^(2))/(9)=45 (whose centre is O),be such that OM is perpendicular to ON then the value of (OM^(2)+ON^(2))/(OM^(2)+ON^(2)) is equal to 3 )
