Note how going from R to S to T to U has us going counterclockwise. In contrast, going from R' to S' to T' to U' has us going the opposite direction going clockwise. This change in orientation strongly implies that a reflection has been done. Reflections always flip orientation.
-----------------------------------------
Here's how we can find the line of reflection.
Draw a line segment from point R to point R'. Mark the midpoint of the segment as point A
Repeat this process to form a segment from S to S'. Mark the midpoint as point B.
The line of reflection will pass through points A and B. This is because the line of reflection is equally distant between the original point (such as point R) and its reflected point (such as R'). This must mean that the line of reflection goes through the midpoint of segment UU' and also segment TT'.
Refer to the diagram below.

Answer:
3.6 > 12/5
Step-by-step explanation:
First, find the decimal value of 12/5
12/5=2.4
3.6 Is greater than 2.4 or
3.6 > 12/5
Hope this helps! :)
Since D is the midpoint of CE, knowing that CD = 3x implies that DE = 3x as well.
So far, we know that:
Now, since AE and BD are parallel, the two triangles ACE and BCD are similar, which means that their corresponding sides are in the same proportion.
For this reason, we can write the following proportion:
and plug the values we wrote above:
Since the two factors in the right hand side are the same, the two factors on the left hand side must be equal as well, so we deduce which solves to .
Knowing that and that , we can easily conclude that .
