The midpoint of JK is M(8,9). One endpoint is J(10, 10). Find the coordinates of the other endpoint K.
Write the coordinates as decimals or integers.
K= (1,7)

Step-by-step explanation:

Given

Midpoint, M = (8,9)

J = (10,10)

Required

Find K

The midpoint of segments is calculated using;

Where and  

Take J as J(x1,y1);

So:

Substitute values for x and y in the given formula

Solving for x2, we have

Multiply both sides by 2

Make x2 the subject of formula

Solving for y2

Multiply both sides by 2

Make y2 the subject of formula

So,

So, the coordinates of K is

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
