Answer:
   10√2
Step-by-step explanation:
A(1, 4), B(3, 6), C(6, 3), D(4, 1)
The distance formula tells you the distance d between two points (x1, y1) and (x2, y2) is given by ...
   d = √((x2-x1)² +(y2-y1)²
Then the side lengths are ...
   AB = √(2² +2²) = √8 = 2√2
   BC = √(3² +(-3)²) = √18 = 3√2
The perimeter is twice the sum of these sides, so is ...
   P = 2(2√2 +3√2) = 10√2 . . . the perimeter of the rectangle
 
        
             
        
        
        
Answer:
x = - 33
Step-by-step explanation:
Given
 (x + 6) = - 18
(x + 6) = - 18
Multiply both sides by 3 to clear the fraction
2(x + 6) = - 54 ( divide both sides by 2 )
x + 6 = - 27 ( subtract 6 from both sides )
x = - 33
 
        
                    
             
        
        
        
The answer is 72°
18 x 2 = 36° 
180 - 36 = 144°
144 / 2 = 72°
