Midoint formula

the midoin between (x1,y1) and (x2,y2) is
( \frac{x1+x2}{2}, \frac{y1+y2}{2})

midpont=11,-22
endoint is 17,-19

(11,-22)=( \frac{17+x2}{2}, \frac{-19+y2}{2})

therfor
11=\frac{17+x2}{2}
-22=\frac{-19+y2}{2}
solve each
times 2 to both sides of both euations

22=17+x2
-44=-19+y2

minus 17 both sides for first
add 19 both sides for second

5=x2
-25=y2

the other endpoint is (5,-25)

Please help me answer this
Ronch [10]

Answer:

10.77

Step-by-step explanation:

by using Pythagoras theorem we can find the distance between the points,

so...

distance between the points, which is the hypotenuse will be xy

difference between the y coordinates will be dy

difference between the x coordinates will be dx

according to pythagoras theorem,

xy^{2} = dx^{2} +  dy^{2} \\xy^{2} = (-6-(-2))^{2} + (-5-5)^{2}\\xy^{2} =(-4)^{2} +(-10)^{2} \\xy^{2} =16+100\\xy^{2} =116\\xy =\sqrt{116} \\xy=10.77
