sum of external angle of a polygon is always 360

external angle is given by 180 - the internal angle

thus the sum of all external angles of this polygon 60+55+50+45+..... = 360

or n/2*(2*60-5*(n-1))=360

on solving for n you get n= 9 or 16

hence the answer e

from your figure: AB/AC = x / R as it is given that AB = BC thus AC = 2 AB thus we have R = 2x Volume of right side of cone = 1/3*Pi*x^2*AB ----(I) Volume of left side of cone = volume of full cone - volume of right side of the cone. = 1/3*Pi*R^2*AC - 1/3*Pi*x^2*AB as R = 2x & AC = 2 AB = 1/3*Pi...

It's the property of a perfect square that: it has only odd number of distinct factors and sum of all these factors is odd. take example of 4; 3 factors : 1,2,4; sum = 1+2+4 = 7 odd 9; 3 factor s: 1,3,9; sum = 13 odd 16; 5 factors : 1,2,4,8,16; sum = 31 odd 25; 3 factors : 1,5,25; sum = 31 odd again
