Answer:

Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:

Solving, we will get a in terms of b:

Now we can substitute a for (b+3) into our equation:

Therefore, the length of each side of this polygon is  .
.
Since the perimeter of the polygon consists of all five sides, the perimeter is:

 
        
                    
             
        
        
        
We have to determine the equation of the line passing through the point (2,-5) and parallel to the line 
When two lines are parallel, then the slopes of the two lines are equal.
Equation of line with point  and slope 'm' is given by:
 and slope 'm' is given by:

Since, we have to determine the equation of a line with point (2,-5).
So, the equation of the line is : 

Since, the line is parallel to the line 
So, 


So, slope of the line  'm' is  .
.
Therefore, the equation of the line is:




Therefore,  is the required equation of the line.
 is the required equation of the line.
 
        
             
        
        
        
Answer: OPTION C.
Step-by-step explanation:
 It is important to know the following:
<u> Dilation:</u>
-  Transformation in which the image has the same shape as the pre-image, but the size changes. 
- Dilation preserves betweenness of points.
-   Angle measures do not change.
 
 <u>Translation:</u>
-  Transformation in which the image is the same size and shape as the pre-image. 
- Translation preserves betweenness of points.
-  Angle measures do not change.
 Therefore, since the Square T was translated and then dilated to create Square T'', we can conclude that the statement that explains why  they are similar is:
 <em>Translations and dilations preserve betweenness of points; therefore, the corresponding sides of squares T and T″ are proportional.</em>
 
        
                    
             
        
        
        
The measure of the third angle is 50 because a triangle has a sum of 180 degrees by angle.
so... 46+84=130 and to get to 180, the last angle has to be worth 50.
