I acc got no idea

[meager river]

do you know what a bearing is

[sharp orchid]

U see my teacher set hw even tho she didnt teach us his

And now if i dont complete it i get a det

So im so lost

So if it goes anticlockwise

How am i meant to even calculate that

When theres no acc coordinates

[meager river]

wait i mean clockwise from north

srry

[sharp orchid]

Oh

Wait so that ain’t far off from 360

[meager river]

yeah

[sharp orchid]

But how would i even calculate it

[meager river]

it gives you unit distances

you can use trig to find the angle of the triangle

[sharp orchid]

I got no cal or even paper on ke

Its like 2 25 am asw 💀

[meager river]

no need for calculator

[sharp orchid]

Oh

[meager river]

do you know your standard trig values?

like sin(30) sin(45)

etc

[sharp orchid]

No 😭

I always js used a cal for it

Teacher js made us do it like that

Even with sohcahtoa

Which i haven’t even done in like 2 years now

[meager river]

you can derive them with triangles

if you're interested

[sharp orchid]

Im acc lost

I got like 300 more questions

[meager river]

ok let's just focus on the question

[sharp orchid]

After his asw 😭

This*

[meager river]

what's the opposite and adjacent sides

[sharp orchid]

Wdym

[sharp orchid]

Oh ic

[meager river]

you can imagine a triangle

find o, a and therefore find an expression for theta

[sharp orchid]

How do i do it without a cal tho

[meager river]

first just, find the ratio

no need for calculator initially

[sharp orchid]

Im actually so lost 😭

I might js get a det atp

[meager river]

ok, just tell me the values of the opposite and adjacent sides

on this triangle

count the squares

[sharp orchid]

2km

And 6

[meager river]

2?

[sharp orchid]

Ye js kill me

U asking for term names or

Cos u said count squares

[meager river]

yes

[sharp orchid]

2 and 6

Is it mot

[meager river]

6 = opposite , 3 = adjacent?

cause it's 3 squares across?

[sharp orchid]

Yea

No other way round

Is it not

[meager river]

look where the angle is

[sharp orchid]

Opposites 2

[meager river]

it's rotated 90 degrees

[sharp orchid]

6 adjacent

Opposites 2

[meager river]

adjacent side means it's adjacent to the angle

opposite means it's opposite to the angle

[sharp orchid]

Yeah so where F is labelled

Is the opposite not here

Then where the adjacent is its where its directly headed

[meager river]

huh

the angle theta is on that side, it's adjacent to that side right?

do you understand?

[sharp orchid]

Would the adjacent not be on the top

Which is 6 squares

Then the opposite next to it

On the side

Then bottoms hypotenuse

[meager river]

opposites aren't always vertical

i think you're confused

[meager river]

what if i rotated the image

[sharp orchid]

Oh

Since its straight

Oopsites 6

Opposite

Then adjacent?

[meager river]

yes

so what trig ratio do we use

if we have opposite and adjacent

[sharp orchid]

Tan

[meager river]

yes

so tan(theta) = opposite/adjacent right?

[sharp orchid]

Uh

[meager river]

i mean 2

[sharp orchid]

First bit i get

But whered u get 1/2 from

[meager river]

mb i meant 2

6/3

[sharp orchid]

Im super lost now

[meager river]

Wdym

wait how do you even solve it without a calculator

it literally says nearest degree

[sharp orchid]

..l

Good point

[meager river]

unless we are supposed to approximate

nvm that's quite difficult to do

[meager river]

oh do you mean you don't have a calculator?

you can just use one on google

[sharp orchid]

Ig

Ill usesafari

[meager river]

but remember

[sharp orchid]

But what do i even calculate @meager river

[meager river]

huh

[meager river]

the angle theta?

you want the bearing

remember bearings always have 3 digits

so if it's 68 then it's 068

[sharp orchid]

OH I FORGOT TO ADD A 0

OMD

[meager river]

oh

do you not get a reattempt?

[sharp orchid]

It aint p68

[sharp orchid]

It switches

If i get it wrong

[meager river]

That was just an example

tan(theta) = o/a so theta = arctan(o/a)

Or inverse tan

[sharp orchid]

Oh..

It switched

But ifi. Recreat the triangle

Its still tan

Difference is

Adjacents 3 riht

@meager river

[meager river]

Wait

It's 2 though?

2 square up

[sharp orchid]

Huh

No its not

Its 3

,

Rip ur off
