Answer:
yes 
Step-by-step explanation:
it just needs to have three sides 
 
 
        
             
        
        
        
A= 80
b= 100
c= 100
a is the same as the 80° already shown and to get b you have to subtract 80 from 180
        
             
        
        
        
In order to get 5%, multiply 62 by .05 and boom you're golden, also it comes out to 3.1
        
                    
             
        
        
        
Answer:
x= 16 and y = 9
Step-by-step explanation:
1 st equation ; x+y = 25
2 nd equation ; x- y = 7
 from 1 st equation 
 x = 25 - y
now putting value of x in 2 nd equation 
x- y = 7
25 - y-y = 7
25 -2y =7
25-7 = 2y
18 = 2y
18/2 = y
y = 9
again
putting value of y in 1 st equation 
x = 25-y
x = 25-9
x= 16
 
        
             
        
        
        
Answer: $166.430 per year 
Step-by-step explanation:
0= -900000+AOC(P/A, 40%,3)
0= -900000+AOC(1.5889)
result we get
AOC= $566430
Require reduction = 566430-400000 
result we get
$166.430 per year
