Answer:

The length of the missing side is

$4 √(5) \\ if \: you \: want \: it \: not \: simplified \: it \: would \: be \: \\ √(80)$

Explanation:

You could do Pythagorean theorem which is:

${a}^(2) + {b}^(2) = {c}^(2) \\ {8}^(2) + {4}^(2) = {c}^(2) \\{64} + {16} = {c}^(2) \\ √(80) = {c}^(2) \\ 4√(5) = c$
