HELP I NEED TO SHOW MY WORK FOR THIS QUESTION!!

The major axis of the
ellipse below has
length of 13. If the
solid line has length
10, what is the length
of the dashed line?

Answer 1

3

Explanation:

The distance from one focus, to any point on the ellipse and then to the other focus = length of major axis

So, 10 + dashed line = 13

Therefore, dashed line = 13 - 10 = 3
