00:03
All right.
00:05
And number seven, we're given an angle of one.
00:08
Now notice, folks, there's no degree symbol here.
00:12
This means we're talking about radiance.
00:14
There has to be that little circle there for it to be a degree measure.
00:19
So we're talking about a radiant angle measure.
00:23
So you need to remember what complementary and supplementary means.
00:28
Complementary means that the angles will add up to 90.
00:32
Well, in radius, that's pi over two.
00:37
So complementary angles will have a sum of pi over two and supplementary that's 180 but in radians 180 is pi.
00:48
So supplementary angles and radians will have a sum of pi.
00:55
So we can set up a couple basic equations right.
00:58
Our given angle plus some complement has to equal pi over two.
01:06
Similar our given angle plus its supplement has to equal pi...
