Answer:
k=4×90=360 degreesAngle for 8 spoke = 8360 =45 degreesAngle for 10 spoke = 10360 =36 degreesAngle for 12 spoke = 12360 =30 degrees(i) As with increasing no. of spokes the angle is decreasing so they are in inverse proportion(ii) Required angle = 15360 =24 degrees(iii) No. of spokes needed = 40360 =9 spokes
