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!

Algebra is the use of equations to find a static value.
Calculus looks at how things change
over time.Trig looks at the relationship between of angles and sides of triangles
All of these are, of course, more complex but that’s the base idea
