Engineers use trigonometry anywhere that involves non-right angles. That includes building cars and buildings, bridges, and many other structures. they also use trigonometry when dealing with fields, like magnetic and electric fields. Also, trigonometry is very important with engineers who deal with waves, such as sound or light engineers.
Many kinds of engineers, navigator, surveyor, architect, air traffic controller, cartographer and many more.
yes they do

Yes
For navigational purposes
Yes.
Trigonometry is used to define triangles, but it is also useful in the representation of waves. Sound engineers, obviously, use deal with sound waves. The pitch, volume, and direction of a sound wave are all deeply rooted in trigonometry.
they us it in computer graphics
Engineers and Physicists use trigonometry, as well as people whose carrers involve acoustics, optics, and waves.

3.14159265 That Pi? Many people use Pi. I use Pi in my math class.
how can trigonometry use in metallurgy
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.
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
