All right.
00:01
Now this one says determine the remaining sides and angles.
00:05
But if you look at your angle measures, now you have so many degrees and so many minutes.
00:10
Okay, so you do need to convert like the 54 minutes.
00:15
Like angle a is 39 degrees and 54 minutes.
00:18
You do have to convert that to a decimal.
00:21
So how you do that, 54 minutes, how many minutes are in an hour? that would be 60.
00:27
That's one revolution.
00:30
So if you divide that by that.
00:31
By 60, oops, 54 to by 60, you get .9.
00:39
So angle a equals 39 .9 degrees.
00:48
Okay, and same thing for angle b.
00:51
So you take 32 divided by 60, and you get .53.
01:03
So that'd be angle b equals 42 .53, right? and then for c, you do the little trick.
01:19
Take 180 minus 39 .9 plus 42 .53.
01:30
Right.
01:32
39 .9 plus 53.
01:38
And then minus 180 from that...
