Step-by-step explanation:
Hey, there!!
Here, one point is A(10,8) and P(8,5) is the midpoint.
Let B(x,y) be the another end point.
Now,
Using midpoint formulae,
[tex]p(x.y) = \frac{x1 + x2}{2} . \frac{y1 + y2}{2} [/tex]
[tex]p(8.5) = ( \frac{10 + x}{2} . \frac{8 + y}{2} )[/tex]
Since they are equal,equating with their corresponding elements we get,
[tex]8 = \frac{10 + x}{2} [/tex]
or, 16 = 10 + x
or, x=16-10
Therefore, x = 6
Now,
[tex]5 = \frac{8 + y}{2} [/tex]
or, 10 = 8 + y
or, y = 2
Therefore, The coordinates of another point are B(6,2)
Hope it helps .....
