1
00:00:06,110 --> 00:00:10,440
Students know the other day the illustration number one.

2
00:00:10,790 --> 00:00:11,650
OK.

3
00:00:12,050 --> 00:00:17,330
So before starting this question I would like to tell you that it is a very basic question which all

4
00:00:17,330 --> 00:00:20,080
students should know how to solve it.

5
00:00:20,120 --> 00:00:27,320
Your study about dignity would be incomplete if you are not able to solve this question.

6
00:00:27,350 --> 00:00:28,250
OK.

7
00:00:28,440 --> 00:00:38,700
I still like this given DNA is equal to free up on for find the other dramatic ratios of angle.

8
00:00:39,500 --> 00:00:44,160
OK so the question is like this.

9
00:00:44,180 --> 00:00:49,850
We have been given one issue that is equal to three by.

10
00:00:50,120 --> 00:00:58,130
And with the help of this D ratio we have to find the remaining DNA shows that is remaining five years

11
00:00:58,520 --> 00:01:00,980
off the angle.

12
00:01:02,060 --> 00:01:11,840
So to solve this question what we have to do we have to first of all take our triangle ABC OK and it

13
00:01:11,840 --> 00:01:13,450
should contain an angle.

14
00:01:13,940 --> 00:01:19,850
It should not be placed at an angle of 90 degree because it is not equal to 90 degrees.

15
00:01:20,000 --> 00:01:25,760
OK so because we are applying to ignore metry we have to take a right angle triangle and we are going

16
00:01:25,760 --> 00:01:28,300
to mark an acute angle as equal to.

17
00:01:28,840 --> 00:01:30,200
OK.

18
00:01:30,260 --> 00:01:36,600
After this what we have to do we have to mark I put news perpendicular albis with respect to this and

19
00:01:36,610 --> 00:01:44,480
get to first of all without any problem you can make the hypotenuse that is the longest side the side

20
00:01:44,480 --> 00:01:46,060
opposite angle of 90 degree.

21
00:01:46,320 --> 00:01:53,450
OK so you'll never face any problem in marking the high point with respect to Engeland the opposite

22
00:01:53,450 --> 00:01:54,690
side is b c.

23
00:01:55,160 --> 00:01:56,980
So it would be the perpendicular.

24
00:01:57,210 --> 00:01:57,870
OK.

25
00:01:58,090 --> 00:02:02,710
And in meetings I can be nothing other than the base.

26
00:02:02,860 --> 00:02:03,270
OK.

27
00:02:03,440 --> 00:02:05,230
So this will be UPI's.

28
00:02:05,330 --> 00:02:07,100
So it is very easy to.

29
00:02:07,370 --> 00:02:10,290
I bought a bendy piece.

30
00:02:10,380 --> 00:02:10,830
OK.

31
00:02:12,010 --> 00:02:19,850
So if you are sure about the opposite side then you can never get the combination wrong.

32
00:02:20,070 --> 00:02:21,100
OK.

33
00:02:21,170 --> 00:02:24,990
So because the end is equal to three by four.

34
00:02:25,190 --> 00:02:31,830
So this can be added and as perpendicular upon base and with respect to the triangle which we have taken.

35
00:02:31,880 --> 00:02:35,320
It can be an equal to B C upon AB.

36
00:02:35,990 --> 00:02:36,680
OK.

37
00:02:37,310 --> 00:02:45,040
So actually be Ze'ev on AB has a ratio equal to three upon four.

38
00:02:45,440 --> 00:02:52,910
OK so this means that easy call that we get that is the length of is equal to 3.

39
00:02:53,000 --> 00:02:55,510
And the length of a is equal to 40.

40
00:02:55,880 --> 00:02:56,500
OK.

41
00:02:56,630 --> 00:03:03,660
So with the help of this regime which was given to us we have calculated the length of the two sides.

42
00:03:03,870 --> 00:03:11,960
And the third side is is known then we know the lengths of all the sides and we can easily calculate

43
00:03:11,990 --> 00:03:12,890
the ratios.
