Let's record what we know about this triangle and what we're trying to find out.
00:05
There are three sides to this triangle, r, s, and t, and three angles, r s and t.
00:16
We can also refer to these sides.
00:18
Instead of using lowercase letters, i can refer to them by the endpoints of the sides.
00:23
So side r is between angles s and t, side s is between angles r and t, and side t is between angles r and s.
00:33
When i'm writing the law of signs, i'm going to use the lowercase letters.
00:37
I think that's a little less confusing, but we need to be able to reference the sides both ways.
00:42
So i've written them both here.
00:44
Now let's see what we know.
00:45
We know that the side between r and t is 582 yards.
00:52
I know that angle t is 32 degrees, 50 minutes.
00:57
And i know that angle r is 102 degrees, 20 minutes.
01:03
And what i'm trying to find is side rs...
