Answer:
The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i ) 
I.e option D  
Step-by-step explanation:
Given equation as :
x² - 8 x + 41 = 0 
For quadratic equation  ax² + b x + c = 0 
The value of x =  
 
∴ For equation x² - 8 x + 41 = 0 
Or,                x =  
 
Or,                x = 
Or,                x = 
∴                  x = ( 4 + 2 i ) , ( 4 - 2 i ) 
Hence The value of x fro the given equation is ( 4 + 2 i ) , ( 4 - 2 i )

Answer:
42° 
Step-by-step explanation:
It is always good to draw a picture to help you.  In this case
tan F = 40/44
m∠F = arctan (40/44) = 42° 
 
        
             
        
        
        
You should plug this into a graphing calculator on your computer! It helps a lot!
