Find x

please help!!​

Answer 1

Answer:
`9√(3)`

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

Step-by-step 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
`√(3)` to get the length of the long leg.

`\text{long leg} = (\text{short leg})*√(3)\\\text{long leg} =9√(3)`

Or you could use the pythagorean theorem to solve
`x^2+9^2 = 18^2` and you should get
`x = √(243) = 9√(3)`
