Question

5. A circular wheel has
twelve spikes (Fig. 11.19).
What is its angle of
rotation and the order of
rotational symmetry?
Fig. 11.19​

Answer 1

Please include the figure with the question or the question cannot be answered.

Answer 2

Step-by-step explanation:

Angle Made By Complete Wheel = 360°

Number Of Spikes = 12

Angle Made By One Rotation = Angle Made By Complete Wheel / Number Of Spikes

Angle Made By One Rotation = 360/12 = 30°

Angle Of Rotation = 30°

Order Of Rotational Symmetry = 12
