Answer: AC=12 cm
Step-by-step explanation:
 To  solve this problem you must apply the law of sines, as you can see below:
 
 Where:
 a=13
 A=85.2°
 B=71.6°
 Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:
 
 
 
        
                    
             
        
        
        
The amount after 2 years is $2,295.
Given that, 
- The invested amount is $1,240.
- The rate of interest is 8%.
- The number of years is 2 × 4 = 8
Based on the above information, the amount after 2 years is 
Future value = Present value ×(1 + rate of interest)^number of years 
= $1,240 × (1 + 0.08)^8
= $1,240 × 1.08^8
= $2,295
Therefore we can conclude that the amount after 2 years is $2,295.

Answer:
1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract  15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
