C. 9 square roots of 2

To answer this question, it's super important that you understand the ratio of sides for special triangles. This triangle in particular, a 45-45-90 triangle, has a ratio between the legs and hypotenuse of 1:1:

Since we are given the value of the hypotenuse, we know that the value of the two sides multiplied by \sqrt{2} will be 18. Knowing this, we can write out an equation:

u*\sqrt{2} = 18

u = \frac{18}{\sqrt{2} }

<u>Multiply both sides by </u>\sqrt{2}<u> in order to get rid of the root in the denominator:</u>

u = \frac{18*\sqrt{2}}{\sqrt{2} * \sqrt{2}}

u = \frac{18*\sqrt{2} }{2}

u = 9\sqrt{2}

If you'd like me to explain how I got to the answer any further, just ask!
