Step-by-step explanation:

First, you find how much 1 cup of flour weighs. You know 5 1/2cups weighs 1 9/16 so u divide that weight by 5 1/2 to find the weight of per cup.

1 9/16 / 5 1/2

You find that each cup weighs 0.2840909091 pounds.

Then you do 35 multiplied by that number to see how much 35 cups of flour would weigh.

35*0.2840909091=9.9431818185

That means a 10 pound bag of flour would have slightly more than 35 cups.

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
