Answer:
X = 35.7 Y=54.3
Step-by-step explanation:
Let the 2 angles be called X and Y were X is the smaller angle
we know that both angles are complementary therefore 
X+Y=90
X = Y - 18.6 ( Given ) 
Y - 18.6 + Y = 90 ( substitution)
2Y = 90 + 18.6
Y = 108.6/2
Y=54.3
X= Y-18.6= 54.3-18.6 = 35.7
Check : X + Y = 35.7+54.3=90

Answer: To find the finance charge you multiply the balance times 0.23 / 12 .
To find the interest charge to an account, you have to multiply the balance by the percent rate (APR). 
The problem in this case is that interest is charged monthly, but the rate is yearly.
To fix this problem, just divide the rate by 12.  
0.23 / 12 
        
                    
             
        
        
        
The perimeter is 36 and the area is 81 units
