Answer:
(x+9)^2 + (y+1)^2 = 100
Step-by-step explanation:
Since the question says diameter, we know the boundary in a circle. Therefore, we just need to find the center and radius.
The center is the midpoint of the two endpoints on a diameter.
Here, it is (-9, -1).
Therefore, the left part of the equation is (x- -9)^2 + (y - -1)^2 = (x+9)^2 + (y+1)^2.
The radius: sqrt(8^2 + 6^2) = 10
So the equation is (x+9)^2 + (y+1)^2 = 100

your questions are out of focus...
Answer:
MJ = 9
Step-by-step explanation:
Since JK is parallel to MN and MN intersects the 2 sides, then MN divides the 2 sides in proportion, that is
= 
, substitute values
= 
( cross- multiply )
20MJ = 180 ( divide both sides by 20 )
MJ = 9
