There is 1 angle between each pair of rays.
So 30 rays equals 30 angles.
But, if the angles are likened to the spokes of a bicycle wheel, should the 30 rays not completely fill the circumference of the wheel, the 2 outer rays also form an angle. So the possible total is 31 angles.

EzraEach pair of rays forms an angle.
If we have 30 rays, the total number of pairs of rays is:
30C2
=435
So, 435 angles are formed in total.

How many nonzero angles are there in a fan of angles that consist of 30 rays?
There are 435 angles in the figure because (30/2)(30-1) is equal to 15 * 29 and the answer is 435
How many non zero angles are formed in a fan of 30 rays with common angles?
Assuming none of the rays meet at 180 degrees, each pair of rays gives rise to two angles: one less than 180 deg and one greater. There can, therefore, be a maximum of 30*29 = 870 angles. (There are 435 unique pairs of rays: ab, ac, ad...bc, bd, be, etc.)
When you trisect an angles you cut the angle into three angles of equal measure with how many rays?
2 rays
