2x + 8 would be the simplified version of this question
        
                    
             
        
        
        
Answer:
   cos(52°) = 18/x
   x = 18·sec(52°)
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that ...
   Cos = Adjacent/Hypotenuse
In this geometry, that means ...
   cos(52°) = 18/x
You can use the relation sec(x) = 1/cos(x) to rewrite this as ...
   x = 18·sec(52°)
_____
You can also use the complementary angle and the complementary trig function.
   sin(90° -52°) = 18/x
 
        
             
        
        
        
Answer:
A
Step-by-step explanation:
p^-8q^-20 * p^8q^-10
=q^-30
=1/q^30
 
        
             
        
        
        
8 because 25% is 1/4 of how much he has so just multiply 2 by 4
