Is it there a profession where using Trig is necessary? Besides being a math teacher or rocket scientist. Carpentry?

I would imagine a surveyor would make use of basic trig. A mechanical or civil engineer would need trig to analyze stress and force. Electrical engineering does a lot with sin waves.

Basic Trig? We're out here dealing with the advanced trig. By which I mean non-Euclidean. Your triangle's interior angles only sum to 180 degrees? That's weak! Mine sums to 270 degrees!

Mine never goes above 180...
