[modest radish]

[somber valley]

that’s not very helpful

neitheris this

[somber valley]

it is literally the first step of working you must do

last time i sent the whole answer and you got angry with me

this time i tell the first step and you are still pointing out my flaws

what do you want

whats a bearing? is it an angle clockwise from north??

[somber valley]

yes

that is a True bearing (the one shown in the question)

[modest radish]

alr

so CBA is 60

[somber valley]

CAB is 60

CBA is not

[modest radish]

wai twha

OHHHH SO IT WAS GOING STRAIGHT DUE NOTH

[somber valley]

because C is directly north of A and B is on a bearing of 60 from A

[modest radish]

alr

so CAB is 60

and then 320 - 60

which is 260

wait what

nvm
