Answer:
option 1 is true. -1/2=-0.5
 
        
                    
             
        
        
        
185% = 185/100
185/100 = 37/20 
The simplest form fraction of 185% is 37/20.
        
             
        
        
        
The square would be 100. 
The semicircle you will use the formula πr^2/2. 
That would mean you would take the 3.14x5^2/2.
(3.14x5x5)/2
(3.14x25)/2
78.5/2
=39.25
So the total area would be 139.25

Answer:
Ah yes rsm.
Anyways, AB is parallel to DE so 72= angle BDE. So BDE+2x+2x=180
72+4x=180
108=4x
x=27
