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.
There are 435 angles in the figure because (30/2)(30-1) is equal to 15 * 29 and the answer is 435
An angle is formed by two rays with a common endpoint.
An angle is formed by a point on the end and two 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.
