Step-by-step explanation:
Since we have a vertical major axis, our ellipse is vertical.
The equation of a vertical ellipse is

where
(h,k) is the center
a is the semi major axis,
b is the semi minor axis
First, let plug in our center

Semi means half, so
a is half of 14 which is 7
B is half of 8, which is 4.

The answer is 5
a^2+b^2=c^2
9+16=25
sq root of 25 is 5
