check out this question on the webpage
http://thinkzone.wlonk.com/MathFun/Triangle.htm and please give me it's solution [THANKS FOR EVEN TRYING]

I haven't the solution, I get the equation x + y = 130, where x and y are angles. If [itex] x, y \in Z^+[/itex]
This is a diophantine equation. We know: x, y > 0. y > x. And y is greater than 90 degrees. the most probable angles: [itex] x=20^o\,\, ,y=110^o[/itex] or [itex] x=30^o\,\, ,y=100^o[/itex]

I tried a couple of things but didn't solve it yet , but there's probably a way to build your way up to the x angle using the tricks in my sketch (just don't have the patience to construct the triangles properly and doing it now):

World's hardest easy problem
Simple geometry is all that is required.
Why can't you do this for yourself? Don't give up so easy.

x+y= 130 reenmachine i agree myself i even not have patience and doing it (doing angle sum property question) , thanks for tip of parallel lines but what benefit it does

If you don't have the patience to try it , I suggest you do not ask others to do it for you as it's not recommended on the forum to ask for answers without showing that you tried hard before hand.I'm not a moderator , just friendly advice.Also , saying that you tried hard is not showing that you tried hard.

You should draw the triangles/angles to scale if you want to try that strategy.
It should look like the picture below

Uff! After long work with a correct precise figure i bored and saw solution on one of other web pages
is it bad of me not getting it (i'm 15 yrs and preparing rmo and iit)
