two third piece a weights 15g find what traction
weights 20g

the of piece a weight is 20g.

Step-by-step explanation:

Let x be the fraction of weight for 20g..

and m be the weight of piece.

Given:

Two third piece a weights is .

That means

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
