The "59" in 819559 rounds up to 60 since 59 is closer to 60 than to 50.

819560

Step-by-step explanation:

the rules of rounding are simple.

since we're rounding to the nearest ten, we take a look at the ones place. if the one is a five or above, we go ahead and round. if it's lower than five, then turn it into a zero, and all the other places stay the same.

the ones place is a nine, so we would round up. turn the one into a zero, and turn the five in the tens place into a six. all the other numbers stayed the same. now, let's just imagine that the nine in the ones place is a three. we round down. turn it into a zero, and all the other numbers stay the same.

hope this helped :)

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
