PLS ANY RESPONSE

1. Please stop using all-caps. On the internet, that’s interpreted as shouting. It’s not polite.

2. Please have patience. No tutors here are online 24/7.

alright

This one is very similar to the one you posted previously.
I gave you a detailed solution, but you apparently did not understand, even
after I clarified it more.

e.g. in the previous problem one of the bearings was 300°. I claimed that
the remaining angle was 60°, and you did not understand it.
Don't know what else to say.
DAVID
I understood it but it was not so clear,well i understand it fully now.thank you
DAVID
do i use the same approach you used for the other question or is there another approach
oobleck
there's always another approach.
complex numbers, vectors, polar coordinates, geometry, algebra, etc.
DAVID
thank you but i don't know the approach to use

DRAW IT
Q is 35 deg w of n
R is 35 deg e of n
so angle QPR = 70 deg
setup for law of cosines

QR^2 = 5^2 + 9^2 - 2*5*9 cos 70 = 25 +81 - 30.8 = 75.2
so
QR = 8.67
Use the law of sines for the rest
I think you want the bearing of R not P from Q and you have a typo
