Answer:
k= -2
Step-by-step explanation:
you are dividing the x by -2 each time
 
        
             
        
        
        
Neither because they are different size and mirrored it could’ve been congruent but it’s double the size and congruent is mirrored and the same size
        
             
        
        
        
Let as consider the complete ques is : Ray QS bisects ∠PQR. Solve for x and find m∠PQR. m∠PQS = 3x ; m∠SQR = 5x-20.
Given:
Ray QS bisects ∠PQR.
m∠PQS = 3x
m∠SQR = 5x-20
To find:
The value of x and m∠PQR
Solution:
Ray QS bisects ∠PQR. So,





The value of x is 10.
Now,



Put x=10,



Therefore, the m∠PQR is 60 degrees.
 
        
             
        
        
        
It's function use the equation with numbers they provided you if they did not use -2,-1,0,1,2 for input and use equation to find output.
