Hi all! I'm a land surveying student and having some trouble with this bearings & azimuths problem in my textbook. Here's what I've worked out. Can anyone help me see where I'm screwing up? The answer I'm getting is 190d 57' 35", but the correct answer should be 150d 00' 28". Thanks in advance!

PSA: Official Answer Key for Genki 3rd Ed (Both Textbooks) Now Available on Amazon (\$15)

I've seen folks asking about this, since the full answer key has yet to be posted online and accessing it requires an account and whatnot. However, it seems the physical version is available on Amazon now for only \$15. It covers both Genki textbooks including all audio exercises.

Must be a recent addition to Amazon US, as I was never able to find it just a few months ago. I ordered mine this week pending starting Genki II soon. If you're studying completely on your own, you will probably need it.

How long should I wait before looking up an answer in a textbook?

I'm an undergraduate who's currently self-studying with an introductory graduate textbook. As such, there is less hand-holding, which I am okay with-- generally I have been able to handle most exercises, or at least have the correct intuitions.

I've read a lot that it's okay to be stumped on problems (especially when the author has not solved all of them, so they may be harder than anticipated); just move on and let them simmer for a while. However, I am still a student with an busy course load that is not designed to be compatible with self studying.

There are certain conceptual goals I'd like to reach before the start of my semester (in February), so I have a deadline, which makes it hard to see how long I should sit on a chapter or just move on. If I move on too early, I may have been able to solve the problem myself; if I move on too late, I won't reach what I wanted to in time.

Do you have any benchmarks you use?

I've been snooping around for an answer key or teacher edition in PDF, and I'm just coming up blank. Can anyone point me to a resource where I can get the answers so I can check my work?

Before anyone says anything, I have Familia Romana on PDF, and I am waiting for a hard copy to be delivered. I am using LLPSI, as well.

Why do textbook publishers have the audacity to exclude answers to challenging problems?

Every student is entitled to the knowledge of whether or not they've answered a homework problem correctly. Its literally impossible to study effectively otherwise. It grinds my gears when textbooks lack a complete answer key. I'm getting tired of this 'every odd question' bullshit. This might make sense if the odd and even-numbered questions are very similar, but they're often not. Some textbooks just exclude large swaths of answers outright (my linear algebra textbook straight up skipped 30 questions in one particular chapter). Its especially maddening if the questions are challenging.
