In the following triangle, we have a is equal to 5, b is equal to 8, and c is equal to 11.
00:10
So we need to find our trig ratios.
00:13
So sign is opposite over adjacent, opposite over hypotenuse.
00:20
Cosine is adjacent over hypotenuse.
00:25
Tangent is opposite over adjacent.
00:29
And then the other one's co -secent is.
00:32
The flip of sign, so that's going to be a hypotenuse over opposite.
00:37
Seekint is the opposite of cosine, so it's going to be hypotenuse over adjacent.
00:42
And cotangent is going to be opposite of tangent, so that's going to be adjacent over opposite.
00:48
So the first three, we're doing it from letter a.
00:52
So from letter a, this is our opposite side.
00:58
This is our adjacent side.
01:00
Oops, adjacent...
