In problem number four, we are given an angle of 22 degrees, 43 minutes, and we are to find both the complement and supplement to that angle.
00:17
So a couple of things you need to remember here.
00:19
First of all, one degree is equivalent to 60 minutes.
00:27
And then, of course, each of those minutes can be divided into 60 seconds.
00:33
And, you know, that's used in navigation, of course.
00:36
And you'll have some homework problems like that coming up.
00:39
But anyway, that helps us when it comes to finding that complement and supplement.
00:46
So we don't have to use the calculator.
00:48
We need it quickly by hand.
00:50
And the other things you have to recall is that complementary angles, those will have a sum of 90 degrees.
00:58
And supplementary angles, those are going to have a sum of 180 degrees.
01:01
So we basically have two simple equations...
