Find x. Write your answer in simplest radical form.

Leokris [45]

Answer:

x = $3\sqrt{11}$

Step-by-step explanation:

Using Pythagorean Theorem we can say;

15² + x² = 18²

225 + x² = 324

x² = 99

x = $\sqrt{99}$

To simplify this in the radical for we can say:

$\sqrt{9*11}$

$\sqrt{9}*\sqrt{11}$

$3\sqrt{11}$

So the answer = $3\sqrt{11}$

Hope this helps!
