the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
Answer:
Proportionality Constant = k = 
Step-by-step explanation:
Equation is:

=> 
Comparing it with
, where k is the proportionality constant, We get:
Proportionality Constant = k = 
I think it is 32, bc the value of x is 20 so your problem would look like this; 2 ( (20) - 4 )
