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.)

What is the relationship between rays and angles?
An angle is formed by two rays with a common endpoint.
What is formed by two intersecting lines or by two rays with a common endpoint?
vertical opposite equal angles
Which of this is formed by two rays with a common endpiont?
An angle is formed by two rays with a common endpoint.
What are angles in geometry?

How many angles are formed by 3 rays that have a common endpoint and no two rays are on the same line?
Six angles.
How many angles of formed by 7 rays that have common endpoints?
3
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.
What is the relationship between rays and angles?
An angle is formed by two rays with a common endpoint.
How many angles are formed by five noncollinear rays with a common endpoint?
21 - including one of 360 degrees.
How many angles are formed by 4 noncollinear rays?
4
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.
What is the sum of the measures of the angles formed by the coplanar rays with the common vertex but with no common interior points?
It is 360 degrees.
What is formed by two intersecting lines or by two rays with a common endpoint?
vertical opposite equal angles
Formed by 2 rays with a common endpoint?
An angle is formed by two rays with a common endpoint.
Which of this is formed by two rays with a common endpiont?
An angle is formed by two rays with a common endpoint.
How many angles are formed by 5 noncollinear rays intersecting at a common end point?
Ten.Each angle is determined by two rays, so the answer is equivalent to the number of combinations of 2 out of 5 = 5*4/(2*1) = 10
