AB¯ is the diameter of circle T. Point A is located at (-4,2) and point B is located at (2,-8). What are the coordinates of the

postnew [5]

Centre is at the middle or the midpoint of the diameter.

And the formula of midpoint is

$( \frac{x_{1} +x_{2}}{2},\frac{y_{1} +y_{2}}{2})$

For the given question, x1=-4, y1=2, x2=2, y2=-8

So we will get

$( \frac{-4+2}{2}, \frac{2-8}{2} ) = (-1, -3)$

And that's the required centre .

Step-by-step explanation:

ΔABC & ΔADE are similar triangles

$\frac{AD}{AB}=\frac{DE}{BC}\\\\\frac{12}{4}=\frac{12}{x}\\$

Cross multiply,

12*x = 12*4

$x=12*\frac{4}{12}\\$

x = 1 * 4

x = 4
