So we have another angle
4,385
902
[]
volunteer
Uh, now we need to have this 3rd angle and we can very easily know which angle it should be because
4,385
903
[]
volunteer
uh, the side is included. The side is between both of these angles. So, uh, if we see this
4,385
904
[]
volunteer
so we do, this one is the
4,385
905
[]
volunteer
side and
4,385
906
[]
volunteer
this is the angle, so another angle should be?
4,385
907
[]
volunteer
uh, tell me, should it be this or this?
4,385
908
[]
volunteer
This is one and this is 2.
4,385
909
[]
volunteer
What do you think
4,385
910
[]
volunteer
The side should be included between these two angles. It should be between the two angles. So should the angle be 1 or 2?
4,385
911
[]
volunteer
2
4,385
912
[]
volunteer
know how to
4,385
913
[]
volunteer
how 2?
4,385
914
[]
student
no
4,385
915
[]
volunteer
No
4,385
916
[]
volunteer
?
4,385
917
[]
student
it would be wrong because of side angle side
4,385
918
[]
volunteer
I think you're confused
4,385
919
[]
volunteer
Yeah, exactly. It would be wrong because of side.
4,385
920
[]
volunteer
No, we
4,385
921
[]
student
and so it is on because angle side angle
4,385
922
[]
volunteer
uh, we are not using side angle side. We are using angle, side angle.
4,385
923
[]
volunteer
Uh, so it is on because
4,385
924
[]
volunteer
uh, it is one, yeah, it's one. I think you mean lung.
4,385
925
[]
volunteer
So yeah, it should be one, right? because uh the site should be between these struggle. If I take this angle, the site is not between these two angles, but if I take this angle, then the side is between these two angles.
4,385
926
[]
volunteer
Uh, so,
4,385
927
[]
volunteer
in this triangle, basically the green triangle that you see.
4,385
928
[]
volunteer
uh angle one is this. What do you think in the blue blue triangle should angle 1B. Should it be the same one, it's basically common in both the triangles, right?
4,385
929
[]
volunteer
Does this make sense
4,385
930
[]
student
yes!
4,385
931
[]
volunteer
Yeah
4,385
932
[]
volunteer
So
4,385
933
[]
volunteer
we just need to name this angle in two different ways, basically, to say that uh it's equal.
4,385
934
[]
volunteer
Uh, I'll just
4,385
935
[]
volunteer
uh erase some stuff from here.
4,385
936
[]
volunteer
So yes
4,385
937
[]
volunteer
uh, in one way I can write this angle is angle CFA.
4,385
938
[]
volunteer
is equal to a DFB.
4,385
939
[]
volunteer
Does this make sense
4,385
940
[]
student
yes I understand the statement
4,385
941
[]
volunteer
What is, I will see if you understood it. And we'll see if a CFA is this angle. The angle DFB DFB again is the same and so we are saying that this angle is equal to this angle, so
4,385
942
[]
volunteer
basically, we are using the reflexive property.
4,385
943
[]
volunteer
Uh, don't you think this should be our statement over here.
4,385
944
[]
student
this cant be reflexive since it would have to be the exact same letters
4,385
945
[]
volunteer
OK, so it needs the same letters.
4,385
946
[]
volunteer
So instead of using the full CFA name, you can simply write on the left, equals angle left.
4,385
947
[]
volunteer
Try this. We can also use this, right?
4,385
948
[]
student
yes! I will try
4,385
949
[]
volunteer
Yeah.
4,385
950
[]
volunteer
So here are the main challenges like uh what will the, the system considered correct because we know the concept and everything, uh, but it's more like what will the
4,385
951
[]
volunteer
that algorithm consider connect
4,385
952
[]
student
yes! it workd
4,385
953
[]
student
thanks!
4,385
954
[]
volunteer
OK, perfect. Uh, do you have any doubt on this problem?
4,385
955
[]
student
no I understand it
4,385
956
[]
volunteer
OK. Um, any other questions?
4,385
957
[]
student
that all for now! Thanks!
4,385
958
[]
volunteer
OK, thank you. Uh, in fact, I also learned so many things today, um, the terminologies and stuff, and it was, it was nice teaching you. Thank you.
4,385
959
[]
volunteer
Have a good night
4,385
960
[]
student
Thank you so much! Have a good night! bye!

Hi
7,645
0
[]
volunteer
hi
7,645
1
[]
volunteer
how can i help you?
7,645
2
[]
student
So I'm doing angular & linear speed problems in pre calc and I don't get them. I have word problems and I can paste one here
7,645
3
[]
volunteer
sure
7,645
4
[]
volunteer
which one?
7,645
5
[]
student
We can start with the first one. Can you also show me how to draw the diagram circle?
7,645
6
[]
volunteer
sure
7,645
7
[]
volunteer
you have to draw a diagram?
7,645
8
[]
student
My teacher doesn't require it but it helps me visualize.
7,645
9
[]
volunteer
oh
7,645
10
[]
volunteer
okay do you know the formula for Distance along the surface between two latitudes
7,645
11
[]
student
s = theta * radius
7,645
12
[]
volunteer
yup
7,645
13
[]
volunteer
so the first one is Sarah
7,645
14
[ { "pii_type": "PERSON", "surrogate": "Sarah", "start": 20, "end": 25 } ]
volunteer
equator
7,645
15
[]
volunteer
but you have to convert the theta from degree to radians
7,645
16
[]
student
so 19.43 * 180/pi?
7,645
17
[]
volunteer
pi/180
7,645
18
[]
volunteer
basically your question says that this angle is given
7,645
19
[]
student
~.339
7,645
20
[]
volunteer
and from this you have to calculate the rest
7,645
21
[]
student
Got it
7,645
22
[]
volunteer
for equator the formula should be theta*pi
7,645
23
[]
volunteer
if you want to convert it to radian you to multiply pi/180 with it
7,645
24
[]
volunteer
what is the result?
7,645
25
[]
student
19.43*pi=61.04
7,645
26
[]
volunteer
then?
7,645
27
[]
volunteer
this is correct
7,645
28
[]
volunteer
but you have to convert it to radian
7,645
29
[]
student
19.43* pi/180 =0.339
7,645
30
[]
volunteer
how?
7,645
31
[]
volunteer
i get it
7,645
32
[]
volunteer
but you missed to multiply it with the radius
7,645
33
[]
student
ooh okay wait
7,645
34
[]
student
so that times 3960 = 1342.91
7,645
35
[]
volunteer
yes
7,645
36
[]
volunteer
perfect
7,645
37
[]
volunteer
you got the first one
7,645
38
[]
student
omg there was confetti
7,645
