The length of the major axis of the ellipse below is 17, and the length of the
red line segment is 6. How long is the blue line segment?

Option C. 11

Step-by-step explanation:

If a point P lies on an ellipse, The sum of distances between the point p and the foci will be equal the major axes.

So, applying the previous rule to the problem

The red line + the blue line = major axis

6 + the blue line = 17

So, the blue line = 17 - 6 = 11

The answer is option C. 11
