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.

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

Six angles.
How many angles are formed in 10 rays?
10 rays can meet in 45 vertices. At each such vertex there will be 4 angles which makes 180 angles in all.
How many angles are there with n rays?
Depends on how many rays you combine but, normally only 1 angle.
How many angles can be draw with three rays?
12
How many angles can be formed by 7 distinct rays?
if the rays have no common points, the answer is zero. if the rays all have the same end point, the answer is 21 -- counting only the acute angles.
How many angles are formed by 4 noncollinear rays?
4
When you trisect an angle you cut the angle into three angles of equal measure with how many rays?
2 rays
How many non-zero angles are formed in a fan of 17 rays?
136 * * * * * Actually there are 17*16 = 272 angles. Assuming the rays do not meet at 180 degrees, each pair of rays forms two angles: one less than 180 deg and one greater.
