Find the length of the third side. If necessary, write in simplest radical form

HERE,
the [tex]\huge{\triangle}[/tex]is a right angle traingle.
length of one side=[tex]\bold{ 1 }[/tex]
length of another side =[tex]\bold{\sqrt{3} }[/tex]
so,
the length of third side=
[tex]\therefore[/tex],the length third side of the traingle is 2.
