Find the value of each variable<br> x = <br> y=
Karolina [17]

Answer:

x=9

y=9\sqrt{2}

Step-by-step explanation:

This is a special type of triangle known as a 45-45-90 triangle.

The ratio for the sides of this triangle are x:x:x\sqrt{2}

Meaning that the two sides other than the hypotenuse are equal, so in this triangle x=9 because it is not a hypotenuse.

The hypotenuse, however, is the value of one side multiplied by \sqrt{2}.

In this case it is 9, so 9*\sqrt{2} = 9\sqrt{2}
