X = 10 opposite sides are equal to eachother
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!!
No pair of 'real' numbers can do that.
The numbers are 'complex'.
They
are
0.5 + 1.936i
and
0.5 - 1.936i .
The symbol ' i ' stands for the
square root of -1 .
