The correct answer is D. D'(1, 5), E'(-1, 3), F'(-1, -4), G'(1, -2).
It's because of this: You need to calculate the distances, and they are in this case symmetric, so you look how far is from one side, and it will be the same on the other side. When you put it on graph, the coordinates are clear and the correct answer is D.
Answer:
The measure of the side 
is 8.8.
Step-by-step explanation:
Since 
, then 
, 
, 
and 
. From figure we have the following relationship:
(1)
Where 
is the proportionality ratio.
If we know that 
, then the measure of side is:
(1b)
(1c)
The measure of the side is 8.8.
