Okay, i want to find the exact values of these trade functions.
00:05
Before i do that, i'm going to find the missing side to this triangle.
00:10
A squared plus 15 square is 17 square.
00:16
That's 225, and that's 289.
00:25
So let's subtract 225 from both sides.
00:34
A square equals 64.
00:37
A is 8.
00:41
Okay, so i'm going to fill that in.
00:44
That is the missing side.
00:47
Cosine is adjacent over hypotenuse.
00:51
Adjacent to theta is the side that measures 8...
