Dilation is the process of making something scaled. In the rectangle with a length of 4 and a width of 2, there is no dilation.
<h3>What is the rectangle?</h3>
A rectangle is a quadrilateral whose opposite sides are parallel and are of equal measurement.
<h3>What is dilation?</h3>
Dilation is the process of making something bigger or wider or scaled.
As we have the length of the rectangle as 4 and the width of the rectangle as 2, which is the same as before as well. therefore, there is no change in the length or the breadth of the rectangle. Thus, we can say that there is no dilation in the length and breadth of the rectangle.
Hence, In the rectangle with a length of 4 and a width of 2, there is no dilation.

Answer:
missing side length is 12
Step-by-step explanation:
similar means that all correlating pairs of sides have the same ratio (old side length) / (new side length).
so, when we know the ratio of one pair, we can apply it to any other side to calculate the correlating side.
we see, when we go from small to large, that we have the ratio 32/40 = 4/5.
so, multiplying the larger side by this, we get the shorter side. 
15 × 4/5 = 3 × 4 = 12
the proportion part in your picture is a bit confusing :
yes,
x/15 = 32/40 = 32/40
I don't know, why this last expression was repeated.
x/15 = 32/40
x = 15×32/40 = 15×4/5 = 3×4 = 12
as you see we get of course the same result doing it that way. 
 
        
             
        
        
        
Well a right angle is 90° so all u have to do is take 10° away from that
