While installing water pipes, Marco had an unknow length of piping. Let p represent the total length of the pipe. If he cut the piping into 5 equal pieces, a) write an algebraic expression that can be used to determine the length of each piece and b)then calculate the length of each piece if Marco starts with a 15 ft pipe.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

25.45584

the answer is 8.64
