1
00:00:00,660 --> 00:00:07,500
Let's do this question two, three, seven meter and four meter high stand upright on the ground.

2
00:00:07,740 --> 00:00:14,470
If their bases are four meter apart, then the distance between their tops is all right.

3
00:00:15,220 --> 00:00:22,230
Now, it's mentioned that the bases are four meters apart and they are now having seven meter and four

4
00:00:22,230 --> 00:00:23,400
meter eight.

5
00:00:23,580 --> 00:00:23,890
Right.

6
00:00:23,940 --> 00:00:24,990
Let's draw the diagram.

7
00:00:27,430 --> 00:00:33,580
So this is a distance between their bases, that's for meter, and this height is given a seven meter

8
00:00:33,580 --> 00:00:36,960
and this height is giving us four meter, we need to find X.

9
00:00:37,170 --> 00:00:37,570
All right.

10
00:00:37,580 --> 00:00:41,040
Pause the video, give it a try and then let's do it together.

11
00:00:42,520 --> 00:00:43,390
All right, we're back.

12
00:00:43,540 --> 00:00:44,950
I hope you've given it a try.

13
00:00:45,280 --> 00:00:47,080
Let's do this constriction.

14
00:00:47,270 --> 00:00:52,660
Let's draw a line parallel to the ground to this point over here that will look like this.

15
00:00:52,930 --> 00:00:55,550
So this distance also will be four meters.

16
00:00:55,840 --> 00:01:00,930
And over here, you're getting a distance of forming over here also.

17
00:01:00,940 --> 00:01:01,240
Right.

18
00:01:01,570 --> 00:01:07,720
This will be four because this total, Heidi, seven meter and because this much is four meter, we

19
00:01:07,720 --> 00:01:10,180
can find that this height over here is three meters.

20
00:01:10,540 --> 00:01:11,650
Now, over here.

21
00:01:12,630 --> 00:01:14,470
Right, that seven minus four.

22
00:01:14,760 --> 00:01:21,060
All right, now over here, we are getting a right angle triangle with sides three, four and six Asper

23
00:01:21,060 --> 00:01:25,490
Pythagoras's Theorem X Square is equal to three squared plus four square.

24
00:01:25,680 --> 00:01:28,440
That's nine plus 16, which is twenty five.

25
00:01:28,650 --> 00:01:33,000
Therefore, X is equal to square root of twenty five, which is equal to five.

26
00:01:33,360 --> 00:01:36,330
And that is your answer, which is option B.
