Hello Friend
Good question
I think the greatest use of trigonometry is finding of distances to nearby stars through the method of parallax. As you know, the Earth orbits around the Sun once a year. This means that at six month intervals the Earth is looking at a star from the two corners of an isosceles triangle (where the point is at the star). We can observe how far the star appears to move against the background galaxies in that time and find the angle of the triangle from that. With the angle and the length ofthe base (the diameter of the Earth's orbit)we can find the height of the triangle - or the distance to the star. See the image below.The movement of the star against the background as we orbit the Sun is called its parallax.
This method can be used in general life to find the distance between you and any other thing.

And comment me to take more example or explanation to this
