1
00:00:00,580 --> 00:00:07,540
Let's do this question A, it is 300 meters above the ground at a moment, it passes vertically about

2
00:00:07,540 --> 00:00:08,260
another kite.

3
00:00:08,500 --> 00:00:14,500
The angle of elevation of the two kites from the same point on the ground is 60 degrees and 30 degrees

4
00:00:15,040 --> 00:00:17,560
in the height of the lower kite from the ground.

5
00:00:18,130 --> 00:00:18,630
All right.

6
00:00:19,000 --> 00:00:22,160
Pause the video, give it a try and then let's do it together.

7
00:00:22,510 --> 00:00:23,420
All right, we're back.

8
00:00:23,620 --> 00:00:24,660
Let's do it together.

9
00:00:24,850 --> 00:00:26,560
We start withdrawing the diagram.

10
00:00:26,950 --> 00:00:28,750
OK, so I have.

11
00:00:29,640 --> 00:00:37,470
The two kids over here, right, let me name these points as A, B, C and D, OK, so what the guide,

12
00:00:37,500 --> 00:00:42,130
which is at the greater height, is at point B and the lower grade is at point C.

13
00:00:42,340 --> 00:00:45,810
OK, now it's given that B is equal to 300 meters.

14
00:00:45,810 --> 00:00:46,200
Right.

15
00:00:46,390 --> 00:00:50,240
And we have to find KDDI, let's CDB equal to X..

16
00:00:50,530 --> 00:00:55,370
Now it's given that the angle of Elevation's are 60 degrees and 30 degrees respectively.

17
00:00:55,410 --> 00:00:55,730
Right.

18
00:00:55,950 --> 00:00:56,340
All right.

19
00:00:56,490 --> 00:00:59,970
Now let's take the length of A.D.s white.

20
00:01:01,330 --> 00:01:08,740
All right, now, what is down 60 to 90 days opposite by Addison, so Tan 60 is equal to 300 divided

21
00:01:08,740 --> 00:01:11,980
by White and we know that and sixty three.

22
00:01:12,110 --> 00:01:13,940
So this is equal to room three now.

23
00:01:13,960 --> 00:01:15,700
Three hundred biophysical rule three.

24
00:01:15,700 --> 00:01:19,010
Therefore why is equal to 300 by road trip.

25
00:01:19,310 --> 00:01:21,940
OK, so this simplifies to the rule three.

26
00:01:22,380 --> 00:01:25,240
OK, now let's find Diane 30.

27
00:01:25,420 --> 00:01:29,260
Sudan is opposite by Addison, Sudan 30 which is this.

28
00:01:29,260 --> 00:01:34,950
The angle over here is equal to X, divided by Y, and we know that Y is equal to one hundred three,

29
00:01:35,110 --> 00:01:38,500
therefore ten thirty is equal to X by under three.

30
00:01:38,770 --> 00:01:42,250
Now we know the value of N30 is equal to one Birute three.

31
00:01:42,370 --> 00:01:42,740
Right.

32
00:01:42,910 --> 00:01:50,890
So let's solve for X and we get X is equal to hundred and therefore 100 meters is the answer to this

33
00:01:50,890 --> 00:01:51,340
question.
