Given:

Now given:
According to Mai
and According to Tyler 
Now we need to find which of them is correct.
So we will solve the given equation we get;

Subtracting both side by 1 we get;

Now Multiplying both side
we get;

Hence both of them are incorrect, correct answer is
.
Well it depends. what the problem
Answer: the root of 145 so b
Step-by-step explanation:
Use S=(n-2)180
S is the sum and N is the number of sides
If you know that the sum is 7560 then plug that in for S
7560=(n-2)180
Then solve for n
7560=180n-360 (note I used distributive property)
7560+360=180n
7920=180n
7920/180=n
n=44 sides
I hope this helps :)
