1
00:00:00,440 --> 00:00:04,160
Let's do this question angle PSR is equal to 50 degrees.

2
00:00:04,370 --> 00:00:12,820
All right, B is the angle by sector of Oreste angle P, Q as is seventy five degrees, find angle PSU.

3
00:00:13,070 --> 00:00:13,510
All right.

4
00:00:13,730 --> 00:00:14,560
Was the video.

5
00:00:14,580 --> 00:00:16,680
Give it a try and then let's do it together.

6
00:00:17,000 --> 00:00:17,420
All right.

7
00:00:17,420 --> 00:00:17,890
We are back.

8
00:00:17,900 --> 00:00:18,820
Let's do it together.

9
00:00:19,040 --> 00:00:25,010
Let's join Q and s alright so we can see that BSR angle P.

10
00:00:25,040 --> 00:00:27,800
S R is equal to Àngel p e right.

11
00:00:27,980 --> 00:00:30,770
Because it's given that piece is the angle dissector.

12
00:00:31,040 --> 00:00:32,690
So let me write that over here.

13
00:00:32,990 --> 00:00:36,440
PSR is equal to Angle PSG and we market over here.

14
00:00:36,440 --> 00:00:38,660
This AngloGold is also fifty degrees.

15
00:00:38,960 --> 00:00:39,410
All right.

16
00:00:39,560 --> 00:00:41,750
Now Angle DSB.

17
00:00:42,080 --> 00:00:46,700
Right, this angle is formed by BIS which is the second and a tangent.

18
00:00:46,700 --> 00:00:47,030
Right.

19
00:00:47,180 --> 00:00:51,590
So as per second tangent theorem this will be equal to angle B.

20
00:00:51,590 --> 00:00:52,010
R.

21
00:00:52,010 --> 00:00:53,570
S right angle.

22
00:00:53,570 --> 00:00:56,090
DSB is equal to angle B r.

23
00:00:56,090 --> 00:01:01,240
S, which is equal to fifty degrees aspecific second tangent theorem to this market over here.

24
00:01:01,250 --> 00:01:02,960
This angle is also fifty degrees.

25
00:01:03,260 --> 00:01:03,740
All right.

26
00:01:03,920 --> 00:01:06,050
Now over here we have two angles.

27
00:01:06,320 --> 00:01:12,860
Now we have a triangle over here, hence angle our as will be 180 minus fifty minus fifty.

28
00:01:13,100 --> 00:01:14,930
That's equal to eighty degrees.

29
00:01:15,560 --> 00:01:15,950
Right.

30
00:01:16,070 --> 00:01:17,990
So that's angle AAPS.

31
00:01:18,230 --> 00:01:20,540
Now you can see that angle P.

32
00:01:20,990 --> 00:01:27,440
S Q will be 180 minus eight minus seventy five.

33
00:01:27,440 --> 00:01:27,770
Right.

34
00:01:27,770 --> 00:01:34,400
Because it's given that angle because that's P q as this angle over here is given a seventy five.

35
00:01:34,610 --> 00:01:34,970
Right.

36
00:01:35,180 --> 00:01:38,540
We have seventy five at and this is the angle that you need to find.

37
00:01:38,540 --> 00:01:44,630
So that would be 180 minus eight minus seventy five which is equal to twenty five degrees.
