8 can go into 71 seven times
8.5, 8/5, 17/25, 82%
because u make them all decimals by dividing them and then do it greatest to least. i’m not totaley sure the order is correct but in decimal form 8.5 = 8.5 bc u don’t have to change it 8/5 = 1.6 and 17/25 = .68 and 82% = .82
Sides:6.7,9.3,9.5

Answer:

Step-by-step explanation:
Split up this Isosceles, Right Triangle into two congruent smaller right triangles. The reflexive side [the line that splits them apart] is 6 units, and both legs are 8 units, leaving the hypotenuses to AUTOMATICALLY be 10 units, according to the Pythagorean Theorem:

With this Pythagorean Triple, we know that our dimensions are correct. Now, to find the perimeter, just add up all the sides EXCEPT for the divider:
![\displaystyle 2[10] + 2[8] = 20 + 16 = 36](https://tex.z-dn.net/?f=%5Cdisplaystyle%202%5B10%5D%20%2B%202%5B8%5D%20%3D%2020%20%2B%2016%20%3D%2036)
