Answer:

Step-by-step explanation:
So an ellipse can be expressed in two different but very similar forms:
<u><em>Horizontal Major Axis:</em></u>
<u><em>Vertical Major Axis</em></u>:

In both equations the length of the major axis is "2a" and the length of the minor axis is "2b"
In the equation you provided, the major axis is horizontal, and the minor axis is vertical.
So looking at the horizontal length, you can see that it's 6, and since this ellipse has a horizontal major axis, that means 2a=6, which means a=3
Looking at the vertical length, you can see that it's 4, and since the ellipse has a vertical minor axis, that means 2b=4, which means b=2
The last thing to note is that the center of an ellipse is (h, k) in the equation, and since here the center is (0, 0) it's (x-0)^2 and (y-0)^2 in the denominator which is just x^2 and y^2
So let's plug in the values into the equation:

(h, k) = (0, 0)
a = 3
b = 2

X/200=65/100
200*65=100x
13,000=100x
x=130
Answer:
<h2>
C. 55 Degrees </h2>
Step-by-step explanation:
The sum of a triangle is 180 degrees. Since you already know two angles, the third one must enable the triangle to equal 180. You first add 83 and 42 together to get 125, and then subtract 125 from 180 to get 55 degrees as your answer.
