Question

complete following no of spikes 4 6 8 10 12 Angel between pairs of consecutive spikes 90° 60°​

Answer 1

Answer:

Angle for 8 spoke = 8/360=45 degrees

Angle for 10 spoke = 10/360=36 degrees

Angle for 12 spoke = 12/360 =30 degrees

(i) As with increasing no. of spokes the angle is decreasing so they are in inverse proportion

(ii) Required angle = 15/360=24 degrees

(iii) No. of spokes needed = 40/360 =9 spokes
