The answer would be 53. This can be found by add 127 twice (xy and uz) and subtracting it from 360. This would give you 106 and you would divide it by 2 for the 2 angles left and get the answer.
        
             
        
        
        
You could use the equation y=mx+b
Find the slope of the two coordinates. I would personally suggest using stack and subtract:
(0,2) 2-5 -3 3
(2,5) -------= ------= -----
 0-2 -2 2
We have the slope but we need to find the y-intercept.
y=3
 --x+b
 2
Plug one of the coordinates in the constructed equation above:
2=3
 -- (0)+b
 2
2=0+b
-0=-0
------------
b=2
We found the slope and y-intercept. Now we have our complete equation. The equation is:
y=3
 --x+2
 2
Have a blessed day!
        
             
        
        
        
Each side area = 54/6 sides = 9 
one side is 3 feet so the volume is 3x3x3 = 27 square feet
        
             
        
        
        
50/100
25/50
1/2
I hope this helps.
