We can see that
there are six sides
so, n=6
so, firstly we will find total angle
total angle =(n-2)*180
total angle =(6-2)*180
total angle =720
so, sum of all angles must be 720
so, we get
now, we can solve for x

There are many ways to do this, I prefer the distance formula it looks like this:
We are given 2 pairs of coordinates: (0,2) and (0,4)
0=x1
2=y1
0=x2
4=y2
We take the numbers and sub in the values above in place of the variables:
Simplfy it:
0^2=0
2^2=4
We are left with :
Final answer: 2
