Firstly, sorry for my silly or simple question, and sorry for my bad English.
I have an arbitrary square which is like this:

Maybe it can be solved with Pythagoras by splitting into two triangle
Can someone please explain me how to solve this problem?


Need to be verify:

and what is the angle between the 1cm side and the 64cm side? or is there 1 more condition? it seems like you forgot to mention something –  Mr.T Jul 9 at 10:02
    
Are the 0.5cm and 1cm sides parallel? –  George Daccache Jul 9 at 10:09
    
yes it is parallel, @Mr.T i just want to ask, what happen if the angle is unknown? The angle between 1cm and 64 cm it is 90.8 degrees. –  Newbie123 Jul 9 at 10:16
    
If the angle is unknown, you can rotate the 1cm side whatever you want (still satisfy the condition of the problem), therefore $x$ is not determined :) –  Mr.T Jul 9 at 10:17
    
@Mr.T Thank you for you explanation :) what if the angle is known like 90.8 (i have updated my image) how to solve it? –  Newbie123 Jul 9 at 10:28
