Answer:
The other endpoit has this cordinadetes (11, 11).
Step-by-step explanation:
Midpoint (MD) (Xm, Ym)
Xm = 5
Ym = 2
Xm of the Midpoint: Xm = X1 + X2/ 2
Ym of the Midpoint: Ym = Y1 + Y2/2
<em>We can say that S is (x1, y1), so x1 = -1 and y1 = -7</em>
Then:
Xm = -1 + x2/2
5= -1 + x2/2
10 = -1 + x2
x2 = 11
Also:
Ym = -7 + y2/2
2 = -7 + y2/2
4 = -7 + y2
11 = y2
The answer is 192 because the middle part is equal to 168 then you add 12 two time for the two side in the right and left so it equals to 192
