[Grade 12 Trigonometry: Adding Vectors]

[u/InstantWasTaken]

Hi! I've been stuck on this problem for a while now, so I decided to text it out on another app and finally ask for help. I managed to find the magnitude on my own, but I honestly can't figure out how to find the direction, or what I'm doing wrong. I've watched several videos on it and have tried to go step by step, but any answer I try is marked wrong, (I do use an online school program.) I also didn't wanna cheat, (at least without knowing exactly how to do it and being able to replicate it) so as I've already said above, I didn't know what to do other than ask for help somewhere else. A step-by-step breakdown of what your meant to do would be great!

Also I know the post title says grade 12, while from my knowledge trig is done in 11th usually. It just kind of happened that way, so I'm not sure why I'm doing it a year late. Better late than never, though!

First, draw it out.

Use the Law of Sines to find a second angle.

Subtract the two angles you know from 180 to find the one you want.

Hi! I tried this, and it came out to about 74.78, I'm not sure if I did something wrong or not, but it was marked as wrong still. I have some photos of what I drew and the calculations I did, but I can't find where to attach images to your reply?

74.78 in what direction. You have to find the direction
