Answer:
The value of RA is " 9.43". 
Step-by-step explanation:
In the given question there is some typing mistake so, the points are:
R =(2, 5) 
A= (-3, -3)
Find: 
RA= ? where it is a distance (D).
Formula:

put the value in the formula:

 
        
             
        
        
        
By definition you have that the tangent of an angle in a right triangle is given by the quotient between the sine of the angle and the cosine of the angle.
 Since we know how much the sine and the cosine measure (we have the sides of the triangles as data), then the tangent is given by:
 A. tan Y= y/z
 answer
 A. tan Y= y/z
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
![\sqrt[3]{-729a^9b^6} =](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-729a%5E9b%5E6%7D%20%3D)




 
        
             
        
        
        
+ is positive, or plus
- is negative, or minus
the third one is multiply, can look like * and "x"
the fourth one is divide, can look like "/"
hope this helps
