Answer: 30 degrees
This is the minimum amount of rotation.
Why this value? Well because 360/12 = 30
Consider a triangle with 3 sides. Specifically I mean an equilateral triangle. We can rotate it 120 degrees to have it line up with itself. Now notice that 360/3 = 120.
For a square, we can rotate it 90 degrees and we can say 360/4 = 90
So the general rule is that the minimum angle of rotation is 360/n, where n is the number of sides. This rule only works for regular polygons. Regular polygons have the same side length and the same angle measure (the side and angle measure won't necessarily be equal).
So going back to this 12 sided dodecagon, we have n = 12 and 360/n = 360/12 = 30 as the minimum angle of rotation. Each 30 degree rotation will have the polygon match up perfectly with its old image. The preimage and image will be identical.
114 + 3=117
117 pages is 1/3 of the book
117×3= 251
So there are 251 pages in the novel.
Answer:
Step-by-step explanation:
''Vedavit walks his dog the same distance each day.''
After 5 days,he has walked his dog 1 mile.''
First we are going to convert the total distance (1 mi) to feet.
The relation is :
After 5 days, he has walked his dog 5280 ft.
The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)
Finally, he has walked his dog each day
Answer:

Tienes suerte, me tomé 5 años de español! Hoep me ayudó!
Answer:
48gallons
Step-by-step explanation:
If 20gallons traveled 440miles.
Then 1gallon will go : 440/20miles
= 22miles.
So for 1054miles : 1054/22 gallon
= 48gallons of fuel will be used.
