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
[tex]x+120+100+128+133+112=720[/tex]
now, we can solve for x
[tex]x+593=720[/tex]
[tex]x=127[/tex].............Answer
