All right.
00:02
So i'm going to be solving a right triangle today.
00:09
Here's a, that's angle c, and this is angle b.
00:17
Found on the top of my screen.
00:23
So what i like to do for this kind of problem is to give myself a sort of answer key template over here.
00:31
Let me say a equals, we don't know angle a yet.
00:35
It's the length of a little a equals 15 .3.
00:40
Angle b equals we don't know that yet.
00:43
Either little b, which is side length b, equals 17 .6.
00:52
C angle c, we actually know that.
00:54
That's 90 degrees because it's a right triangle.
00:57
And we're still looking for side length c.
01:02
So, better fix that.
01:14
This one is 15 .3, and this one is 17 .6.
01:25
Now, if you're looking for side length c, you might as well use pythagorean theorem.
01:31
Since we have that available.
01:36
You know that a squared plus b squared equals c squared.
01:47
I've been amazed by the way at how this formula never goes away even in advanced calculus.
01:53
You'll keep seeing that come up over and over again...
