Answer 1

Answer:  $9\sqrt{3}$

==========================================================

Explanation:

For any 30-60-90 triangle, the short leg is always half the hypotenuse.

This makes the short leg to be 18/2 = 9 units long.

We then multiply this by $\sqrt{3}$ to get the length of the long leg.

$\text{long leg} = (\text{short leg})*\sqrt{3}\\\text{long leg} =9\sqrt{3}$

Or you could use the pythagorean theorem to solve $x^2+9^2 = 18^2$ and you should get $x = \sqrt{243} = 9\sqrt{3}$
