What is the angle of rotation for a regular 15-sided polygon?

1 answer:

7 0

The angle of rotation is the smallest angle of rotation a polygon can make until it goes back to its original figure. This could be determined by dividing a whole revolution by the number of sides of the polygon. A whole revolution is 360 degrees. If we divide this by 15, the angle of rotation would be 24 degrees.

For every day that passes it falls back another 1 second

So once it is 21 seconds behind all you have to do is subtraction to find the amount of days past

21 - 12 = 9

Answer:

80.

Step-by-step explanation:

Let $C$ be the set of people who like cats and $D$ the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the $(C$ ∩ $(D$ , you have n $(C$ ∩ $(D$ = n(C) + n(D) - $(C$ ∪ $.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C$ ∩ $(D$ $= 190 +141 -251 = 80$
