Answer:
The answer would be, 2.75
Step-by-step explanation:
Add all the numbers up:
0+1+1+2+3+4+5+6=22
Divide the answer by the amount of numbers:
22÷8=2.75
I can’t see the tea really good
A polygon is any figure sided with three sides and above such that triangle (3) is the smallest polygon. A nonagon is a polygon with 9 sides. To get the sum of interior angles of a polygon we use the formula;
(n-2) 180 or (n-4)90 where n is the number of sides.
Therefore, for a nonagon the sum of interior angles = (9-2) 180 = 1260 degrees
If we add all the angles we should get 1260, considering the remaining angles to be each x
Thus 138+154 +145 +132 +128 +147 +130 + x +x =1260
= 974 + 2x = 1260
= 2x = 286
= 143
therefore, each of the other angles was 143
Answer:
-2x^2
Step-by-step explanation:
Simplify
x^-1 - 2x^2 - x^-1
becomes
-2x^2
