What is the x? Like what is the name of the x that I am looking for. cated x is opposite of v. And I know the tan. Then what Am I looking for sinus or cosinus?

Help me out with both if yall can

blissful frigate Jul 17, 2024, 5:44 PM

#

length of side

#

btw Tan theta = Oppostie/Adjacent

tribal arch Jul 17, 2024, 5:52 PM

#

@blissful frigate what am I lokking for

#

Cos or sin

#

?

blissful frigate Jul 17, 2024, 5:52 PM

#

u have to look for x

#

the side

#

length

tribal arch Jul 17, 2024, 5:53 PM

#

Is x cos or sin

blissful frigate Jul 17, 2024, 5:53 PM

#

x is the side length

tribal arch Jul 17, 2024, 5:53 PM

#

or is x neithet

#

Ab/ac?

#

If not whats the formula

blissful frigate Jul 17, 2024, 5:54 PM

#

do you know what tan theta is?

tribal arch Jul 17, 2024, 5:55 PM

#

No@blissful frigate

#

I dont

#

This is one of the first questions

#

In the book

blissful frigate Jul 17, 2024, 5:55 PM

#

wait a min

#

tribal arch Jul 17, 2024, 5:56 PM

#

That ik

#

The adj and opp

#

X is opp of angle v

blissful frigate Jul 17, 2024, 5:57 PM

#

Sine theta is Opposite/Hypotenuse, Cos theta is Adjacent/Hypotenuse and Tan theta is Opposite/Adjacent

#

yes x is opposite

tribal arch Jul 17, 2024, 5:57 PM

#

blissful frigate Sine theta is Opposite/Hypotenuse, Cos theta is Adjacent/Hypotenuse and Tan thet...

Ye

blissful frigate Jul 17, 2024, 5:57 PM

#

Adjacent is 3 root 3

tribal arch Jul 17, 2024, 5:58 PM

#

Yes

blissful frigate Jul 17, 2024, 5:58 PM

#

And tan theta is given as 2/5

tribal arch Jul 17, 2024, 5:58 PM

#

Yes

blissful frigate Jul 17, 2024, 5:58 PM

#

so, x/3root3=2/5

#

plugging the values in the formula for tan theta

tribal arch Jul 17, 2024, 5:59 PM

#

X : 3sqrt3=2
3 5

#

?

#

Which formula do i use

#

IS the question

blissful frigate Jul 17, 2024, 5:59 PM

#

tan theta

#

is given as 2/5

tribal arch Jul 17, 2024, 6:00 PM

#

Ao the formula for tang

#

Why not cos

#

Or sin

blissful frigate Jul 17, 2024, 6:00 PM

#

with the given values, we can only fing tangent

#

as we dont have hypotenuse and angle v is unknown

tribal arch Jul 17, 2024, 6:01 PM

#

I see

#

Its the same in the other task?

#

The one under

blissful frigate Jul 17, 2024, 6:02 PM

#

no, in the one under, you have to use a calculator

#

tan 35.5= x/8.5

#

what answer did you get for first one?

tribal arch Jul 17, 2024, 6:04 PM

#

blissful frigate tan 35.5= x/8.5

Isnt the formula the same

blissful frigate Jul 17, 2024, 6:04 PM

#

ya, its the same formula

tribal arch Jul 17, 2024, 6:04 PM

#

blissful frigate what answer did you get for first one?

I didnt solve it, because I am tryna understand what im doing before that

#

Tan=ab/ac?

#

Or opposite/adjacent

blissful frigate Jul 17, 2024, 6:04 PM

#

tribal arch I didnt solve it, because I am tryna understand what im doing before that

ya

tribal arch Jul 17, 2024, 6:05 PM

#

Because I know that u can use the degree aswell

#

But how

#

Like degree a is 30 degrees

blissful frigate Jul 17, 2024, 6:05 PM

#

as we have value for tangent we dont need the degree in first question

#

@tribal arch understood?

tribal arch Jul 17, 2024, 6:07 PM

#

Aha

#

Or nah

tribal arch Jul 17, 2024, 6:07 PM

#

blissful frigate as we have value for tangent we dont need the degree in first question

Aha

#

But didnt understand

blissful frigate Jul 17, 2024, 6:07 PM

#

what

tribal arch Jul 17, 2024, 6:07 PM

#

Like first one u dont have angle vakue

#

This is so confusing

#

The 1st one u have the tangent

#

Secind u dont

#

And its the same fornula

blissful frigate Jul 17, 2024, 6:08 PM

#

Yeah, at first, trigonometry is confusing

#

Wait, I'll explain with an example

tribal arch Jul 17, 2024, 6:09 PM

#

Ok ok

#

Confusikg rn

#

But much easier than derivation

blissful frigate Jul 17, 2024, 6:10 PM

Watch a yt video in the meanwhile

blissful frigate Jul 17, 2024, 6:10 PM

@blissful frigatefirst task

#

is 2/5*3sqrt3?

blissful frigate Jul 17, 2024, 7:00 PM

#

yah, you got it

#

now find the 2nd one

tribal arch Jul 17, 2024, 7:02 PM

#

the 2nd one

#

is

#

@blissful frigatehelp pls

#

0 clue

#

im cooked

blissful frigate Jul 17, 2024, 7:08 PM

#

okay, so go to a calculator and find the value of tan 35.5

tribal arch Jul 17, 2024, 7:09 PM

#

like in mty head

#

the anwser is

#

ab/ac

#

=8,5/tan 35,5

#

approcaimately 19,4

#

10,4

blissful frigate Jul 17, 2024, 7:09 PM

#

Tan 35.5 = x/8.5

#

tan= opp/adj

#

so x is opposite

#

8.5 is adk

#

adj

#

so x = tan 35.5 * 8.5

#

understood?

tribal arch Jul 17, 2024, 7:11 PM

#

hmm

blissful frigate Jul 17, 2024, 7:11 PM

#

approximately 6.06

tribal arch Jul 17, 2024, 7:11 PM

#

i got that to

#

but the book said its 6,10

in b

blissful frigate Jul 17, 2024, 7:14 PM

#

i dont know german, sorry

tribal arch Jul 17, 2024, 7:14 PM

#

is it the hypotenus being tan 2/3

#

Its tehe same qustion

#

find the x

#

is hypotenus being 2/3

blissful frigate Jul 17, 2024, 7:14 PM

#

its a different one

tribal arch Jul 17, 2024, 7:14 PM

#

or is it another part

#

fuck

blissful frigate Jul 17, 2024, 7:14 PM

#

tan v is 2/3

tribal arch Jul 17, 2024, 7:14 PM

#

what then

blissful frigate Jul 17, 2024, 7:15 PM

#

opp is 8

tribal arch Jul 17, 2024, 7:15 PM

#

tan v 2/3= bc/av?

#

ab under

blissful frigate Jul 17, 2024, 7:15 PM

#

tan v = 2/3= 8/x

tribal arch Jul 17, 2024, 7:16 PM

#

8/X

#

like in a fraction?

blissful frigate Jul 17, 2024, 7:17 PM

#

sorry x= 8*3/2

#

= 24/2=12

tribal arch Jul 17, 2024, 7:18 PM

#

what

#

isnt it 24/3

#

@blissful frigate u have the same anwser as in the book

#

but why 2 under

#

not 3

blissful frigate Jul 17, 2024, 7:20 PM

#

2/3=8/x

#

yes or no?

tribal arch Jul 17, 2024, 7:20 PM

#

8/x like in a fraction?

blissful frigate Jul 17, 2024, 7:20 PM

#

ya

#

8 is opposite

tribal arch Jul 17, 2024, 7:21 PM

#

whaa

#

can uwrite it

blissful frigate Jul 17, 2024, 7:21 PM

#

x is adjacent

#

in tan

tribal arch Jul 17, 2024, 7:21 PM

#

on a paper?

#

i dont understand

#

do u have a piece of paper close

blissful frigate Jul 17, 2024, 7:23 PM

#

ya doing it

tribal arch Jul 17, 2024, 7:24 PM

#

ty

blissful frigate Jul 17, 2024, 7:26 PM

#

#

sorry for bad handwriting

tribal arch Jul 17, 2024, 7:28 PM

#

its a good handwriting

#

I understand everything untill 2/3=8/x

#

why 2x=8x3

#

u mean 8*3?@blissful frigate

blissful frigate Jul 17, 2024, 7:29 PM

#

ya

tribal arch Jul 17, 2024, 7:30 PM

#

why is it 2x

#

the x was under the 8

blissful frigate Jul 17, 2024, 7:30 PM

#

multiply both sides by 3*x

tribal arch Jul 17, 2024, 7:30 PM

#

first *3

#

thjen *x`?

blissful frigate Jul 17, 2024, 7:31 PM

#

ya

#

when multiplied by 3, the 3 under will cancel out in 2/3

tribal arch Jul 17, 2024, 7:32 PM

#

yes but how can the fraction be gone

#

of 8

#

we dont know wat x is

#

it could be 100000

blissful frigate Jul 17, 2024, 7:32 PM

#

we multiplyy by 3 and x

#

x cancels out

tribal arch Jul 17, 2024, 7:33 PM

#

so x cancels out the fraction

#

basically

#

yes

blissful frigate Jul 17, 2024, 7:33 PM

#

ya

tribal arch Jul 17, 2024, 7:33 PM

#

I see now

#

dammn ur smart u know so much of this shit

blissful frigate Jul 17, 2024, 7:33 PM

blissful frigate Jul 17, 2024, 7:35 PM

#

ya, use calculator

tribal arch Jul 17, 2024, 7:35 PM

#

ok but how

blissful frigate Jul 17, 2024, 7:35 PM

#

use tan inverse i think

#

is answer 21.80 approx?

tribal arch Jul 17, 2024, 7:36 PM

#

idk

#

what is the uinput

blissful frigate Jul 17, 2024, 7:37 PM

#

#

use the one under tan

#

k?

tribal arch Jul 17, 2024, 7:38 PM

#

blissful frigate Jul 17, 2024, 7:39 PM

#

arc tan

tribal arch Jul 17, 2024, 7:39 PM

#

i got it now

#

Why arctan

#

not tan

#

whats teh diff

blissful frigate Jul 17, 2024, 7:39 PM

#

tan^-1

#

we find angle with arctan

tribal arch Jul 17, 2024, 7:39 PM

#

aaa

#

this is getting easy at this point

#

im gonna be a smart girlie
