Answer: 1/14 in simplest form
One rotation has 360 degrees. Since regular Pentagon has 5 sides and each of them takes 360/5=72 degrees when looked from center, if we rotate regular Pentagon by 72 degrees we will get same shape as we started from.
Therefore answer is 72 degrees.
The width would be 9 inches. Here's how I got the answer:
Double 12
Subtract from total
Take your difference and divide by two.
That will give you the width.
75.339
nearest tenth: 75.3
nearest hundredth 75.34
nearest whole number 75
Scale factor is equal to 1/2, since the point went from 10 to 5
