Okay, so on this one, again, you're giving angles in degrees and minutes.
00:05
So you first need to convert those minutes to a decimal form of degree.
00:14
So there's 60 minutes in one revolution of the hand of a clock.
00:18
So you're going to take 18 divided by 60 and get the decimal form of that.
00:26
Point three.
00:27
So angle c equals 79 .3.
00:34
Same thing for 57, so 57 divide by 60 is .95.
00:44
So angle a is 32 .95.
00:51
So angle b, right? for angle b, you just take 180 minus 79 .3 plus 32 .95.
01:08
Right.
01:10
79 .3 plus minus 180 and you get 67 .75 degrees.
01:24
So now you got to find little a, little b, little c i know i kind of wrote this out of order.
01:33
They give you one of them.
01:34
Now little c is 39 .81 because you don't have to find that one...
