Okay, so i see that you need help with this question and this is very like once you know one angle or a couple of the angles, you know how to find the rest of the angles.
00:14
So the measurement of angle eab is 95 degrees.
00:20
So eab, so that's this angle measurement, okay, is 95 degrees, okay.
00:29
Then the measurement of bed is 80 degrees.
00:33
So bed, so that's these three angles, okay.
00:41
That is a total of 80 degrees, okay.
00:47
So i have this one and this one.
00:49
The measurement of angle one is 83 degrees.
00:52
So one is 83 degrees.
00:58
Then i have angle three is 101 degrees.
01:04
So this one is 101, 101.
01:09
So this one is 101, which means that this angle here, so if i do 360 minus 101 minus 101, then that's 158 divided by two.
01:27
So this one is 79 and this one's 79.
01:34
Then, so i have this one.
01:38
Measurement of angle five is 46 degrees.
01:43
So this here is 46 degrees.
01:48
And then angle seven is 35 degrees.
01:54
So this is 35 degrees.
01:58
Then abc is 104.
02:01
So abc, so this whole angle here is 104 degrees, okay.
02:10
Then it says that, just going to change to a different color, ac and cd are perpendicular.
02:22
So that means that this angle is 90 degrees, okay.
02:28
Which means that these three angles, if you add them together, are 180 degrees.
02:33
So this angle here plus those two angles, so 180 minus 90 minus 46 is 44 degrees.
02:48
So then measurement of angle two is 62 degrees.
02:54
So if this is 62 degrees, this one right here, then this angle right here, this tip of that angle is 80 minus 62.
03:12
Let me just go over this, 62 degrees.
03:16
So then this one is 18 degrees, okay.
03:23
And then measurement of angle four is 104 degrees.
03:26
So if this is 104 degrees, then this is 104 degrees.
03:30
Which means that 180 minus 104 is 76.
03:39
So this is 76 and then this is 76.
03:46
Then, so i got the 104.
03:51
And then measurement of angle six is 70 degrees.
03:56
So that means that 180 minus 70 degrees minus 35, that's 75 degrees, okay.
04:13
So if this is 75 degrees, that's 18.
04:17
So 180 minus 18 minus 75.
04:21
So this angle here is 87 degrees, which means that this is 87 degrees.
04:26
Which means that 360 minus 87 minus 87, divide that by two.
04:35
So this is 93 degrees.
04:38
This is 93 degrees.
04:40
So then 180 minus 93 minus 70 is 17 degrees.
04:47
Which means that this also is 17 degrees, because 17 plus 87 plus 76 is 180.
04:54
If this is 44 and that is 104, so 180 minus 104 minus 44, and that's 32 degrees.
05:08
Where else? so then i have, if this is 83 degrees, then this is 83 degrees, and so 360 minus 83.
05:26
83 minus 83 divided by 2, and that is going to be 97 degrees and 97 degrees.
05:38
And so then this here, if i have 183, 360 minus the 101 minus 97 minus 62.
05:52
Then this is 100 degrees, which means this is 100 degrees.
05:58
Which means that 360 minus 200.
06:03
And so then this is 80 degrees, and then this angle measures 80 degrees.
06:09
That's 18, so 180 minus 80 minus 18.
06:15
So that's 82, is this one...
