So we have side b, side c.
00:02
We need all three angles.
00:04
Well, we need two, because we know that c is the right angle, so that's 90 degrees.
00:11
And let's see, we know that.
00:14
We have this acronym, set of acronyms.
00:17
Sokatoa, which is the sign of the angle is equal to the opposite over the hypotenuse.
00:24
The cosine of the angle is equal to the adjacent over the hypotenuse.
00:30

00:34
Side.
00:36
Let's see.
00:37
I want to find, i'm going to look at angle a.
00:41
I'm going to look for angle a...
