Not much. In any case, you won't need advanced math (like trigonometry, algebra, calculus, logarithms...) which you only use in science and engineering careers.

Depending on your career, you may or may not need trigonometry. If your job does not require a lot of math, it is unlikely that you will use trigonometry very often, however, this is not a reason not to study it. The skills and discipline developed in your trigoometry class will help you no matter what career you choose.
how can trigonometry use in metallurgy
One example of an astronomer's use of trigonometry is determining the distance to a star by triangulation.
Mechanics use trigonometry to find angles mostly used in body or chassis work.
Well, if Edward Cullen the bloodsucking vampire can use trigonometry. Then I am asuming farmers can as well.
The first recorded use of trigonometry came from the Hellenistic mathematician Hipparchus
An architect who designs a bridge would use trigonometry, among other mathematical techniques.
