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: 2/7 of a gallon (in decimal it’s 0.286)
Step-by-step explanation: This one’s really easy.
2/7 of 1 gallon. Checking: so that if you multiply it by 7 it equals to 2
Answer: 21 cm
Explanation: it doesn’t make sense if the missing side was 45 cm because it’s shorter than the other sides and their measurements are 34 and 28 cm
It would just be y=3600 I believe. Don’t overthink it bud
Formula is length x breadth x height
11 x 5 x 6= 330
330 is the surface area
