Hi there!
We can use right-triangle trigonometry to solve. 
We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance. 
cosθ = Adjacent/Hypotenuse
We can plug in what is given:
cos(28) = A/17 
Solve for 'A':
17cos(28) = <u>15.01 ft</u>
 
        
             
        
        
        
Estimate of 2854 = 3000
so 3000 times 9 = 27000
        
                    
             
        
        
        
4. is A 15
5. is C 12
6. is B 4, 8, 12, 16
hope this helps :)

Answer: The cost will be the same on month 5.
Step-by-step explanation:
x = number of months 
50 + 100(x) = $550
200 + 70(x) = $550
x = 5
