00:00:00.000 --> 00:00:07.000
Alright, so this problem, what we're going to try to do is we're going to try to find,
2
00:00:07.000 --> 00:00:14.000
let's actually give these some lengths, let's give this a point a, b, and c.
3
00:00:14.000 --> 00:00:22.000
Let's try to find the length of a, b. So one thing that we, I'll give you some more point here.
4
00:00:22.000 --> 00:00:29.000
One thing we know is the length from b to c is 1.6 and the whole distance is four meters.
5
00:00:29.000 --> 00:00:36.000
So what I can do is, if I want to find the missing length, what I'll do is I'll take a, c, the length of a, c,
6
00:00:36.000 --> 00:00:45.000
and I'll subtract the length of b, c. So what that looks like is a, b equals a, c is how long?
7
00:00:45.000 --> 00:00:54.000
Four meters minus 1.6. Alright, and meters.
8
00:00:54.000 --> 00:01:03.000
Therefore four minus 1.6 is going to give me 3.4 meters.
9
00:01:03.000 --> 00:01:07.000
So just remember when you have a hole in that part, and you're trying to find that other part,
10
00:01:07.000 --> 00:01:10.000
and they both make up when added together, they're going to make up the hole.
11
00:01:10.000 --> 00:01:14.000
They're not like it's shown in this line statement. You can just take the hole,
12
00:01:14.000 --> 00:01:24.000
and then you can just subtract your part to get your other part.
