(k/3^k)(x-6)^k
for this series determine whether it is convergent or not .if convergent find radius of convergence

converges by the ratio test for

The limit is 1, so the series converges as long as

which indicates a radius of convergence of 3.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
