Answer:
   16.9 units
Step-by-step explanation:
Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...
   14.87 + 2 = 16.87 ≈ 16.9 . . . units
_____
The distance formula can be used to find the lengths of individual segments. It tells you ...
   d = √((Δx)² +(Δy)²)
where Δx and Δy are the differences between x- and y-coordinates of the segment end points.
If the segments are labeled A, B, C, D, E in order, the distances are ...
   AB = √(5²+1²) = √26 ≈ 5.099
   BC = √(1²+3²) = √10 ≈ 3.162
   CD = Δx = 3
   DE = √(3²+2²) = √13 ≈ 3.606
   EA = Δy = 2
Then the perimeter is ...
   P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867
   P ≈ 16.9
 
        
             
        
        
        
Answer:
C)  6 inches
Step-by-step explanation:
(√72)² = x² + x²
72 = 2x²
72/2 = x²
36 = x²
√36 = √x²
6 = x
x = 6 inches
 
        
                    
             
        
        
        
Answer: the answer is A) AC~=FC
Step-by-step explanation:
to answer that both triangles are congruent using SSS (Side-side-side) postulate, you have to show that each corresponding side is the same.
