Answer:
c
Step-by-step explanation:
12.50*6=75
45.25*3=135.75
135.75+75=210.75
 
        
                    
             
        
        
        
To solve this problem you must apply the proccedure shown below:
 You must apply the Pythagorean Theorem. 
 a) Taking 28 inches as the hypotenuse of the right triangle (the largest side), you have:
 a^2=b^2+c^2
 Where "a" is the hypotenuse, and "b" and "c" are the other sides of the right triangle.
 Then, you have:
 a=28 inches
 b=15 inches
 c^2=a^2-b^2 
 c=√(a^2-b^2)
 c=23.6
 Therefore, the answer is: 23.6 inches
 a) Taking 28 inches as a one the other sides that are smaller than the hypotenuse, you have:
 a=√(b^2+c^2)
 Where "a" is the hypotenuse
 a=31.8 inches
  The answer is: 31.8 inches
        
                    
             
        
        
        
$2,812 will be the final value of the account

2. DE 1/2 AB - side splitter theorem
3. CD/CA = CE/CB - sst = proportioned sides
        
                    
             
        
        
        
Hi!
I would approach this question by first looking at where the parallelogram is located, by graphing the image. I did so and drew a rough image on Paint (See attached image)
To get the part where the diagonals intersect, I would find the midpoint of the line between points (1, 3) and (5,-9) (or the other pair). The reason is a parallelogram's diagonals always bisect each other, meaning the point they intersect is always the middle of the two diagonals.
Therefore, you can find the midpoint of a diagonal, between (1, 3) and (5, -9). The midpoint theorem is ( .
.
Take the points (1, 3) and (5, -9), and fill them in.

Then solve.

(3, -3)
If you'd like to check the other midpoint:
Take the points, (8, 3) and (-2, -9)

Then solve.

(3, -3)
They're the same, so that answer is correct.
Hope this helps!
