Answer:

The coordinates of point D( 4,4)

Explanation:

Step(i):-

Given points are E(10,4) and B(16,4)

'E' is the mid-point of segment BD

Let D(x₁, y₁) be a point

E = midpoint of segment BD


(10,4) = ((x_(1) +x_(2) )/(2) , (y_(1) +y_(2) )/(2) )


10 = (x_(1) +16 )/(2)

20 = x₁ + 16

20-16 = x₁

x₁ =4

Step(ii):-


(y_(1) +y_(2) )/(2) = 4


(4 +y_(2) )/(2) = 4

4 + y₂ = 8

y₂ = 8-4 =4

The co-ordinates of point D( 4,4)
