ANSWER
The correct answer is C
.
<u>EXPLANATION</u>
We have

and
.
We solve the two equation simultaneously by elimination method. We need to be smart and eliminate y, since we are looking for
.
We first multiply equation (2) by 2
.
We add equation (3) and (1).
.
Dividing through by 6 gives

Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
