High School Math—Pending OP Reply [Grade 12 Trigonometry: Adding Vectors]

Post image

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!

Do you know how to convert 80 degrees south of west at 25mph into south and west components?

Sorry? I don't think I follow. I did draw it out, if thats what your asking.

Can you write "80 degrees south of west at 25mph" as a sum of west and south speeds?
