Sagot :
value of n could be 252 degree. Option 4
How to determine the value
It is important to note that a decagon is a ten-sided polygon.
Since, a decagon has 10 sides
And we know that the angle made in one complete rotation is 360 degree.
Now find angle made in each rotation by the decagon is 360,
= 360/ 10
= 36 degrees
Now, we have to find possible values of n, and 'n' must be a multiple of 36
Apply hit and trial from given options.
We observe that from given options, only 252 degree is multiple of 36.
Therefore, value of n could be 252 degree. Option 4
The complete question is ;
A regular decagon is rotated n degrees about its center, carrying the decagon onto itself. The value of n could be:
1. 10 degrees
2. 150 degrees
3. 225 degrees
