Answer: G=4
Step-by-step explanation:
 
        
             
        
        
        
For full circle area is π * R² [here R = radius],
for a sector of circle with angle β, area will be = (β/2) * R², β is in radian,
here let β = 22.5° = (π * 22.5/180) = π/8 radian,
now [(π/8)/2] * R² = 9π, [π/16] * R² = 9π
R² = 9 * 16 = 144, 
R = √144 = 12 m
        
             
        
        
        
The three interior angles of any triangle add to 180 degress.  Therefore,
180-(120 + 40) = the third angle.
So, 20 is the third angle
