You could just use your calculator thats on your phone of tab
We can't answer the question, you haven't given us the information, we need to know what the x is here, or if they gave you a value.
All you have to do is add up the side lengths we already know then subtract by the perimeter.
60.3 is the side lengths all together that we know
82-60.3=21.7
Hope this helped!!
