Answer:
D(4,-3)
Step-by-step explanation:
Given three of the vertices of the square: A(4, -7), B(8, -7),C(8, -3)
Let the coordinate of the fourth vertex be D(x,y).
We know that diagonals of a square are perpendicular bisector. So, the midpoint of both diagonals is the same.
The diagonals are BD and AC
Midpoint of BD = Midpoint of AC

The coordinates of the fourth vertex is D(4,-3)
Answer:
Step-by-step explanation:

50 is little away from 49 and 50 is far away from 64.

As 50 is closer to 49 the square root of 50 will be closer to 7 than 8 and so it should be just a little over 7
√50 ≈ 7.1
