Answer:
x = 100
Step-by-step explanation:
(x - 20) + x = 180
2x - 20 = 180
<u> + 20 +20</u>
2x = 200
x = 200/2
x = 100
We have been given that an ellipse has a center at the origin, a vertex along the minor axis at (0,-8), and a focus at (15,0). We are asked to find the equation for the ellipse.
The standard from an ellipse centered at origin with major axes at x-axis is , where
a = Horizontal radius,
b = Vertical radius.
Since focus is at x-axis, so our ellipse will be a major horizontal axis.
Horizontal radius will be equal to distance from origin to point (15,0) that is
The vertical radius would be distance from origin to point (0,-8) that is:
Upon substituting values of a and b in above equation, we will get:
Therefore, our required equation would be .
