how can trigonometry use in metallurgy
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.
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.
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.
How large is a triangle? The real-life uses of trigonometry extend far beyond mere simple right-triangles into great expanses of scientific and engineering maths in everyday professional use, so "how" you would collect the data would depend on the specific study.

you would use subtraction in the real world if you have money. Let's say you have $20, you want to buy something for $17. how much money would you have left? answer:$3

it is used in real life situation to fin the height of thing and in math you use it to find the length of one of the sides.

Well, if Edward Cullen the bloodsucking vampire can use trigonometry. Then I am asuming farmers can as well.

Yes.
yes they do
