Question

Help please?? <3
What are the foci of the following graph?

Answer 1

first you need to find the focal length
\[f=\sqrt{a^2+b^2}\]
a=5
b=2

Answer 2

that segment is the focal length once you found it
you can find the coordinates of the two foci

Answer 3

I got f=sqrt(29) or
f≈5.38516481 but I don know what to do after that
