1
00:00:00,880 --> 00:00:09,490
Let's do this question, the angles between south and east and north, east and northwest are all right

2
00:00:09,670 --> 00:00:10,140
over here.

3
00:00:10,150 --> 00:00:11,290
We have two angles.

4
00:00:11,470 --> 00:00:14,560
This is the first angle, which is the angle between south and east.

5
00:00:14,830 --> 00:00:20,420
And this is the next angle, which is between the direction northeast and northwest was the video.

6
00:00:20,680 --> 00:00:22,990
Give it a try and then let's do it together.

7
00:00:23,650 --> 00:00:24,040
All right.

8
00:00:24,040 --> 00:00:24,510
We're back.

9
00:00:24,520 --> 00:00:25,820
I hope you have given it a try.

10
00:00:26,080 --> 00:00:31,390
This is a basic question, but it helps to solidify our understanding of the fundamentals.

11
00:00:31,660 --> 00:00:33,400
Let's press on over here.

12
00:00:33,400 --> 00:00:40,300
We have the four directions north, south, east and west, north and south are opposite to each other.

13
00:00:40,600 --> 00:00:42,580
East and west are opposite to each other.

14
00:00:42,760 --> 00:00:48,580
And you can know that the angles between north and east or eastern, south, south and west and west

15
00:00:48,580 --> 00:00:51,430
and north are all 90 degree angles.

16
00:00:51,760 --> 00:00:52,180
All right.

17
00:00:52,510 --> 00:00:59,380
Now, when we talk about the directions north, east and north west, this is the direction north east,

18
00:00:59,380 --> 00:01:06,910
the direction north east is dividing the angle between north and east in equal halves for this angle

19
00:01:06,910 --> 00:01:07,840
is forty five degree.

20
00:01:08,560 --> 00:01:12,670
And similarly, this angle over here is also forty five degrees.

21
00:01:13,070 --> 00:01:13,540
All right.

22
00:01:13,690 --> 00:01:15,550
Now let's mark our angles.

23
00:01:15,700 --> 00:01:22,270
As for the question, this is angle one and this is angle to the angle between northwest and north east.

24
00:01:22,270 --> 00:01:23,770
That's one of the angles mentioned.

25
00:01:23,950 --> 00:01:27,730
Let's call that angle one and the angle between south and east.

26
00:01:27,730 --> 00:01:28,900
That's the other angle.

27
00:01:28,900 --> 00:01:30,160
Let's call it angle two.

28
00:01:30,580 --> 00:01:33,790
Now, why is this angle over here also?

29
00:01:33,790 --> 00:01:34,510
Ninety degrees.

30
00:01:34,810 --> 00:01:40,780
It's because North West also divides the angle between north and west in equal halves.

31
00:01:41,050 --> 00:01:45,160
But this is also equal to forty five degrees and this is also equal to forty five degrees.

32
00:01:45,370 --> 00:01:51,250
Therefore, the angle between north west and north east is forty five plus forty five, which is also

33
00:01:51,250 --> 00:01:52,560
equal to ninety degree.

34
00:01:52,720 --> 00:01:57,280
And similarly we have seen that the angle between South and east are also ninety degree.

35
00:01:57,460 --> 00:02:01,790
So over here both the angles are equal to ninety degrees.

36
00:02:02,110 --> 00:02:08,920
Now when we are these together, angle one plus angle two is equal to 90 plus 90, which is equal to

37
00:02:08,920 --> 00:02:09,800
180 degrees.

38
00:02:10,030 --> 00:02:16,090
That means these angles are supplementary and the correct option is answer B.
