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
What is an angle formed by two opposite rays that measure 180 degrees?
supplimentary angles
What is two angles whose sides are opposite rays?
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
When you trisect an angle you cut the angle into three angles of equal measure with how many rays?
2 rays
Two angles whose sides are opposite rays are?
Vertical angles
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 are formed by 12 distinct rays with a common endpoint?
There are 66 angles formed by 12 distinct rays with a common endpoint. The first ray by itself doesn't make an angle, the second ray makes 11 distinct angles, the third ray makes 10, the fourth 9, the fifth - 8, the sixth - 7, the seventh-6, the eighth - 5, the ninth- 4, the tenth - 3, the eleventh - 2, and the twelfth - 1 (it makes an angle with the first ray).
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 of formed by 7 rays that have common endpoints?
3
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.
What are angles in geometry?
An angle is formed by a point on the end and two 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.
When you trisect an angles 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 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 an angle formed by two opposite rays that measure 180 degrees?
supplimentary angles
