That depends on how complex your world is. If you become an unskilled worker you may never use math past basic arithmetic ever again. However, you may be dependant in your work on machines such as cash reginsters, computers, etc, that required trig in their development. If you become a skilled worker such as a carpenter, plumber, surveyer, etc you will use basic trig on an intuitive level in your work. And if you go on to college and into a profession that uses science, you'll find trig used in many fields.

In real world there are two aspects controlling human awareness and related activities. They are number and language, which together works towards addinng a precise human awareness. It is a direct answer to your question also.
We shall now go to number applications!
A study of triangles (trignometry) adds great number-application skills to people which is easiest by relating with 2D-matrix positions.
Sine, cosine, tanjent...etc need external assistance to arrive at an answer which computers do for us now!
one method to mentally relate infinitesimal angular steps is given below which is technically 'application of sine, cosine... ' whereas it differ from a usual equal-angularar-units!
Application is given below!
Each 2D square matrix 0...9, or 00...99 or 000...999 or a higher order has digonal positions which are steps of 9 or steps of 99 or steps of 999 or a higher order!
A matrix 0...9 has 'one of its diagonal positions' as 09, 18, 27, 36, 45, 54, 63, 72, 81, and 90 which are merged 'y' and 'x' values. In other words y/x = either 0/9. or1/8, 2/7, 3/6, 4/5...8/1, 9/0. It is a trignometry relation.
When said points are related to 'origin' we get vectors that varies in a order. Said vectors are not equal-angle-step variations but mentally computable a-unit step variations, which is not used now!
Said application can be remembered easily by 'y+x' = either 9 or 99, or 999 or a higher order, and (y+1) *9 or 99 or 999... = y, x ( a merged value). It enable to remember y/x relations which is another way to apply trignometry mentally. It computes finer angular steps! Modern relating of degree minute, second is too large steps to relate 'positions of material worlds in universe' whereas human-mind and logic does it effortlessly.
a practical application is.
Take 2D-matrix 00000...99999
Take a diagonal position 12345 87654 (every fifth digits pair sum is 9 and there are 5 sums)
y/x of position 1234587654 = 12345 / 87654 = tan theta with respect to origin of said matrix! We can mentally relate all 99999 vectors like it. Never try to solve fractions y/x if it is not an absolute need!
The higher is the matrix you relate the finer is angular a-unit steps! There is no limit of refinement!
You can also relate 3D-cube matrix-linked applicatios, which will depend on your ability to imagine utility of of 'said knowledge' for endless applications! If you have no needs; a knowledge might appear useless. So always ask a question to yourself as;
What is relavance of my own knowledge?
When you get an answer to it yoursef! You will find real world!

There are particularly truly some circumstances. the finest to come back to ideas contain calculating forces. as an party, in case you push diagonally hostile to an merchandise, you may favor to calculate the stress ingredient in a particular route. truly some the time you are able to only use undeniable Pythagoras' Theorem, yet each now and then you'll favor to do it with triangles that are literally not suitable-angled. being able to calculate the area of a triangle is fairly significant, no longer least because maximum different gadgets could properly be decomposed into triangles so as that it truly is an helpful issue to have in, as an party, approximating the end results of calculus issues.

Easy way to determine the height of a tree or mountain or the width of a river.

in topography
in physics
and more
suppose you know the high is some vertical pylon and also you know the visibility angle then you can calculate the distance from you to the pylon d=h/tan(alpha)
