Answer:
12
Step-by-step explanation:
6 are striped which is half of them, the other half must be 6 then 
6+6=12
 
        
                    
             
        
        
        
Rectangular form:
z = -2.1213203-2.1213203i
Angle notation (phasor): 
z = 3 ∠ -135°
Polar form:
z = 3 × (cos (-135°) + i sin (-135°))
Exponential form: 
z = 3 × ei (-0.75) = 3 × ei (-3π/4)
Polar coordinates: 
r = |z| = 3 ... magnitude (modulus, absolute value)
θ = arg z = -2.3561945 rad = -135° = -0.75π = -3π/4 rad ... angle (argument or phase) 
Cartesian coordinates: 
Cartesian form of imaginary number: z = -2.1213203-2.1213203i
Real part: x = Re z = -2.121
Imaginary part: y = Im z = -2.12132034
