Answer:

(0 ,3)

Step-by-step explanation:

Midpoint = (0,4)

Endpoint C= (0,5)

Endpoint D = (?, ?)

[tex](0.4)=(x ,y)\\\\(0,5)=(x_1,y_1)\\\\(x_2,y_2)= ?\\\\x = \frac{x_1+x_2}{2}\\ \\0 = \frac{0+x_2}{2}\\ \\Cross\:Multiply\\0 =0+x_2\\0-0=x_2\\\\x_22 =0\\\\y = \frac{y_1+y_2}{2}\\ \\4 = \frac{5+y_2}{2}\\ \\Cross\: multiply\\8 =5+y_2\\\\8-5 =y_2\\\\3 =y_2[/tex]
