Coordinates of the midpoint of AC:
M ( (-6-2) / 2) , ( 7-9 ) /2 ) = ( -4, -1 )
d ( BM ) = √ ( 4 + 4 )² + ( -1+ 1 )²
d ( BM ) = √ 8 ² =√ 64 = 8
The length of the median from angle B is 8.

Answer:
Hey if its not for a grade why do it??
Step-by-step explanation:
The distance between two points (x₁,y1),(x₂,y₂) is d
![d= \sqrt{(x2-x1)^2 + (y2-y1)^2}](https://tex.z-dn.net/?f=d%3D%20%5Csqrt%7B%28x2-x1%29%5E2%20%2B%20%28y2-y1%29%5E2%7D%20)
For the given problem we have
<span>W(1,8),X(7,8),Y(4,5), and Z(1,2)
The length of WY = </span>
![\sqrt{(4-1)^2 + (5-8)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%284-1%29%5E2%20%2B%20%285-8%29%5E2%7D%20)
= 3√2
The length of WX =
![\sqrt{(7-1)^2 + (8-8)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%287-1%29%5E2%20%2B%20%288-8%29%5E2%7D%20)
= 6
The length of WZ =
![\sqrt{(1-1)^2 + (2-8)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%281-1%29%5E2%20%2B%20%282-8%29%5E2%7D%20)
= 6
The length of XY = <span><span>
![\sqrt{(4-7)^2 + (5-8)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%284-7%29%5E2%20%2B%20%285-8%29%5E2%7D%20)
= 3√2
</span>The length of ZY = </span><span>
![\sqrt{(1-4)^2 + (2-5)^2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%281-4%29%5E2%20%2B%20%282-5%29%5E2%7D%20)
= 3√2
∴ WX = WZ ⇒⇒⇒ proved
XY = ZY ⇒⇒⇒ proved
WY = WY ⇒⇒⇒ reflexive property
∴ Δ</span><span>WYZ is congruent to ΔWYX by SSS method</span>
