Ответ:
so, 52 + 244 + 144 + 70 + 81 + 272 + 97 + 200 + x = 1260
1160 + x = 1260
x = 100
In short, Your Answer would be 100
Hope this helps!
Ответ:
The formula for finding the sum of interior angles for any polygon is (n-2)*180
where "n" is the number of sides.
So, plug in 9 for n.
9-2 = 7
7 * 180 = 1260
Now , subtract all the known interior angles from 1260.
After subtracting all the known interior angles from 1260 you should be left with 100.
This means that the value of x is equal to 100°
