Use the Pythagorean theorem, tan is y/x so y = -3 and x= -2. Because cos is negative and R is always positive. You need to find R- which is the hypotenuse;
3^2 + 2^2 = r^2
9 + 4 = r^2
13 = r^2
√13 = r.
So you already have tan<span>θ, 
cot</span><span>θ= 2/3
sin</span>θ= -3/√13 BUT
you have to rationalize, so you get -3 √13/ 13
cscθ= √13/ -3
cosθ= -2/ √13 BUT
you have to rationalize, so you get -2√13/ 13
secθ= √13/ -2
        
                    
             
        
        
        
0.4%, turn it into a decimal, which is 0.004
0.004*100= 0.4 
        
                    
             
        
        
        
Answer:
The borrower will pay back $4,136.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
 .
.
In this question:
Loan amount of 1760, so 
Interest rate of 13 and one half, so 13.5%. This means that  .
.
10 years, so 
Interest on the Loan:

Total amount:

The borrower will pay back $4,136.
