The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
Answer:
88
Step-by-step explanation:
43 + 49= 92.
Then 180 - 92= 88
C= 88
You can predict 132 people will get a glazed donut.
explanation: if you divide 288 by 24 you get 12. with that you multiply 11 times 12 and get 132 which would get you to a fraction of 132/288.
Answer:
18
Step-by-step explanation:
Well, you said 12. Since the exact result is roughly 11.76, and you can't have 76/100ths of a person, it has to be 11.
