Answer:
let remaining angle in heptagon be a.
a+64=180(linear pair)
a=116
again
x+155+90+163+a+121°=720(sum of interior angle of hexagon is (6-2)×180°)
x+529+a=720
x+116=720-529
x=191-116=75
Your answer would be x-4=17.
4 less than (#) is 17.
That number would be 21.
21-4=17
Hope that helps
the estamated answer is 775
Answer
7.53
1,227 then divide that by 163 so
1,227÷163= 7.53 so then you would go
163 and multiply 7.53 and you would get 1,227
