You can go fors years without ever using trig. But let's say you were building a wooden deck and you wanted to be sure it was square. You could by ensuring the diagonals were equal. How did the Egyptians get perfect right angles? The used rope triangles with sides = 3,4,5.
Say you want to paint your house and need to figure the square feet of the walls including the pointy ends. Trig again.
You need a ladder to reach 16 feet up while leaning at 30 degrees. How long a ladder do you buy?
I'm a carpenter, so I use it frequently.
You can get through life without it, but occasionally in comes in handy.

They can be useful. It depends how you live your life, what questions you ask yourself about the things around you & what things in life interest you.
For example, trig functions helped me to figure out why the shadow of my house spread out over my garden so rapidly in the evening when I was planning to go lie in the sun. (It's to do with tangents & the height of the sun in the sky.) Also, using the sine function helps me figure out whether it's my imagination or not when the sunsets seem to be getting earlier at an increasing rate at some times of the year.
There are other examples I could give. I can't think of anything essential to living unless you're planning to go into engineering, science or mathematics professionally or as a hobby.

You may not use trig functions directly, but everything else in your civilization does - everything that uses electricity (AC current is a sine wave), all your plumbing ["solid waste" don't run uphill], your food supply [growing seasons are periodic functions], and endlessly so on.

Not much use.
Arithmetic is has the greatest utilisation in our daily life. Next is elementary algebra.

Trigonometry is very useful while constructing buildings,
without it u'd have to use very complicated tech.

This was the thing which I could not understand, when I was studying higher mathematics

Well, you wouldn't use it to be honest, but learning it well helps you do well in GCSE Maths.
