To find the hypotenuse,we can use the Pythagoras Theorem:
[tex]{c}^{2} = {a}^{2} + {b}^{2} [/tex]
Where c is the hypotenuse and a,b are the legs.
In this case:
[tex]{c}^{2} = {3}^{2} + {3}^{2} \\ {c}^{2} = 9 + 9 \\ {c}^{2} = 18 \\ c = \sqrt{18} [/tex]
Therefore the answer is Square root of 18 units.
Hope it helps!
