There are 435 angles in the figure because
(30/2)(30-1)
is equal to 15 * 29
and the answer is 435

When you trisect an angles you cut the angle into three angles of equal measure with how many rays?
2 rays
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 can be draw with three rays?
12
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 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.

Six angles.
How many angles are there in 30 rays?
900
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 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 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 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.
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.)
