00:00:00,680 --> 00:00:09,260
Let's do this question in the following figure, FBI is parallel to B.C. Is Baladi an experiment to

2
00:00:09,260 --> 00:00:09,740
E.T.?

3
00:00:09,980 --> 00:00:15,900
We need to find the value of X over here, pause the video, give it a try, and then let's do it together.

4
00:00:16,190 --> 00:00:16,640
All right.

5
00:00:16,640 --> 00:00:17,060
We're back.

6
00:00:17,090 --> 00:00:18,320
I hope you've given it a try.

7
00:00:18,740 --> 00:00:21,370
Let's mark the information that is given to us.

8
00:00:21,920 --> 00:00:24,720
We know these three lines are parallel, right?

9
00:00:24,890 --> 00:00:30,550
Because it's mentioned over here and we know Acey is parallel to E.T. It's given over here.

10
00:00:30,890 --> 00:00:31,370
All right.

11
00:00:32,030 --> 00:00:35,780
Now in Triangle ABC, we have two anchors.

12
00:00:35,960 --> 00:00:39,380
That's 52 degrees over here and sixty four degrees over here.

13
00:00:39,620 --> 00:00:45,130
Therefore, we can say that angle C is equal to 180 minus fifty two plus sixty four.

14
00:00:45,470 --> 00:00:48,620
That's equal to sixty for what we have found.

15
00:00:48,620 --> 00:00:53,000
Angle C now angle one and Anglesey are equal.

16
00:00:53,000 --> 00:00:58,520
Right, because he is parallel to ABC and AC is acting as the transversal.

17
00:00:58,700 --> 00:01:04,370
Therefore Angle one and Anglesey are alternate interior angles and hence they are equal.

18
00:01:04,550 --> 00:01:08,120
And we have found that angle C is equal to sixty four degrees over here.

19
00:01:08,540 --> 00:01:08,960
All right.

20
00:01:09,110 --> 00:01:16,900
Now angle one plus angle X will give you 180 degrees because over here you have AC parallel to you deep

21
00:01:17,120 --> 00:01:19,580
and is acting as the transversal.

22
00:01:19,730 --> 00:01:25,190
So these are consecutive interior angles and we know that they add up to 180 degree.

23
00:01:25,340 --> 00:01:28,230
So angle one plus angle X is equal to 180 degrees.

24
00:01:28,610 --> 00:01:32,180
And over here we see that angle one is equal to angles.

25
00:01:32,330 --> 00:01:34,290
So this is sixty four degrees, right.

26
00:01:34,430 --> 00:01:38,990
So sixty four plus X is 180 or X is 180 minus sixty four.

27
00:01:39,140 --> 00:01:41,420
That gives you one one six degrees.
