Answer:
44
Step-by-step explanation:
Given:

Required:
Average range of change from 3 to 9
SOLUTION:
Step 1:
Find f(3) and f(9):
To find f(3), replace x with 3 in the given function




To find f(9), replace x with 9 in the given function




Average rate of change = 
Where,


Plug in the values into the formula for average rate of change.



Average rate of change = 44
I would say m∠TBS= 52°
SV=15
m∠TCV=52° as well
this is my best guess
