Answer 1

just use theorem pythagoras

Answer 2

The third side is 3√6 units.

Explanation:

Given that this is a 90° triangle so you can apply Pythagoras Theorem :

`{a}^(2) + {b}^(2) = {c}^(2)`

`{a}^(2) = {c}^(2) - {b}^(2)`

`{a}^(2) = {( √(90)) }^(2) - {6}^(2)`

`{a}^(2) = 90 - 36`

`{a}^(2) = 54`

`a = √(54) = √(9 * 6) = 3 √(6)`
