I don't know if we can find the foci of this ellipse, but we can find the centre and the vertices. First of all, let us state the standard equation of an ellipse.
(If there is a way to solve for the foci of this ellipse, please let me know! I am learning this stuff currently.)

Where

is the centre of the ellipse. Just by looking at your equation right away, we can tell that the centre of the ellipse is:

Now to find the vertices, we must first remember that the vertices of an ellipse are on the major axis.
The major axis in this case is that of the y-axis. In other words,
So we know that b=5 from your equation given. The vertices are 5 away from the centre, so we find that the vertices of your ellipse are:

I really hope this helped you! (Partially because I spent a lot of time on this lol)

The measure of AN form the given figure is 2. 5cm. Option D
<h3>How to determine the length</h3>
It is important to note that if from one external point, two tangents are drawn to a circle then they have equal tangent segments.
We have that,
AM ≅ AN
so, if AM measures 2. 5cm
AN measures 2. 5cm
Thus, the measure of AN form the given figure is 2. 5cm. Option D

The length of the segment ac is 10.3 cm
<h3>How to determine the length ac?</h3>
The segments are given s:
ab = 7.8cm
bc = 25mm
Point b is located between points a and c.
So, we have:
ac = ab + bc
Substitute known values
ac = 7.8cm + 25mm
Express mm a cm
ac = 7.8cm + 2.5cm
Evaluate the sum
ac = 10.3 cm
If the point b lies on segment ac, then there can be only one solution

Answer:
it's a /
Step-by-step explanation:
Answer: subtract 2 and then multiply 2 then spuare root both sides then subtract 5
