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 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
What is the relationship between rays and angles?
An angle is formed by two rays with a common endpoint.
What are angles in geometry?
An angle is formed by a point on the end and two rays
How many angles in 30 rays?
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 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.
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 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.

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.)
