# Q3. Rehman is making a wheel using spokes. He wants to fix equal spokes in such a way that the angles between any pair of consecutive spokes are equal. Help him by completing the following table.(iii) How many spokes would be needed, if the angle between a pair of consecutive spokes is$40^{\circ}$ ? Number of spokes     4     6    8    10  12 Angle between a pair of consecutive    $90^{\circ}$   $60^{\circ}$   ....     ....  ....

If the angle between a pair of consecutive spokes is $40^{\circ}$  then,
Number of spokes needed would be $\frac{360^{\circ}}{40^{\circ}}=9$
