Question

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

Answer 1

6

Explanation:

its a right angle so to find a side use a Pythagorean theorem

Pythagorean theorem =

`a^2+b^2=c^2`

`a^2+b^2` are the sides

`c^2` is the hypotenuse

In this case we need the hypotenuse

`3√(3) ^2 + 3^2 = c^2`

`27 + 9=c^2`

`36=c^2`

the opposite of squaring is square rooting so:

`√(36) =6`

therefore the answer is 6 ^-^
