Number of occurrences of a given angle formed using 3 vertices of a n | Function that calculates occurrences of given angle that can be created using any 3 sides.
Maximum angle in a regular n - gon is equal to the interior angle If the given angle is greater than the interior angle then the given angle cannot be created.
The given angle times n should be divisible by 180 else it cannot be created.
Initialise answer.

#Here is code to number of occurrences of a given angle formed using 3 vertices of a n and the other steps required.
 def solve ( ang , n ) :
	if ( ( ang * n ) > ( 180 * ( n - 2 ) ) ) :
		return 0
	elif ( ( ang * n ) % 180 != 0 ) :
		return 0
	ans = 1
	freq = ( ang * n ) // 180
	ans = ans * ( n - 1 - freq )
	ans = ans * n
	return ans
