I have here a triangle drawn with the longest side labeled as l, the medium side as m, or the middle side is m, and the shortest side of it than s.
00:11
And also i've included the information that it gave us that the shortest side is 77 miles less than the middle, and that the longest side is 374 miles more than the middle.
00:24
We know the perimeter of all of these will add up to be 3 ,066.
00:30
I'm going to go ahead and set up an equation that only has one variable.
00:35
So i know that the middle side plus the middle plus 374, which is the longest side, plus the middle side minus 77, will all end up equaling 366.
00:49
I'm going to combine like terms, so i see that there are three ms.
00:53
And i have 374, basically minus 77, which will give us.
01:00
I can see that this is going to have to be regrouped a few times.
01:06
297 as positive.
01:09
All right, and that equals the 3 ,066.
01:13
If i subtract 297 from both sides, let's see what we have here.
01:22
So that gives us 9, 29, 15, 6, 7, 2...
