If the foci of th

Answer :

To find: value of b2


Given: foci of given ellipse and hyperbola coincide







Formula used:


Coordinates of the foci for standard ellipse is given by (±c1, 0) where


Coordinates of the foci for standard hyperbola is given by (±c2, 0) where


Since, their foci coincide




Here a1 = 4, b1 = b,






b2 = 16 – 9


b2 = 7
