Answer:
2/3
Step-by-step explanation:
0.05 kilogramos.................
The answer is x is less than or equal to 3. the first answer choice
The sum of the measures of all exterior angle in a polygon with n sides is always
.
Nonagon is a polygon with 9 sides. If this nonagon is regular or equiangular, then all interior angle are congruent, and therefore all exterior angles are congruent. Then the measure of each exterior angle is
.
