Answer:
Solutions are -10 and 26 
Step-by-step explanation:
( - the abolute sign I'm using 
( x - 8 ) + 2 = 20 
( x - 8 ) = 18 
x - 8 = 18 (postive case)
 x - 8 + 8 = 18 + 8
x = 26 
( x - 8 ) = 18 
x - 8 = -18 (negative case)
x - 8 + 8 = -18 + 8 
x = -10

i ^1 = i
i ^ 2 = - 1
i ^ 3 = - i
i ^4 = 1
etc.
................
"i" raised to an odd power cannot simplify to be : A ) - 1
        
                    
             
        
        
        
Step-by-step explanation:
x = 90- 55 = 35
y = 180- x 
y= 180 - 35 = 145
z =180- (y +10)
z = 180 - (145 +10)
z = 180-155
z = 25
