Use the formula of a distance between two points:


Answer:
None of these.
Step-by-step explanation:
8/x is the result when 8 is divided by x.
This is a picture of how you solve the equation
Since it's a right triangle you can use the Pythagorean theorem or Trig (Soh Cah Toa).
I'll just use the Pythagorean theorem : a² + b² = c²
a = 9
b = x
c = 18
9² + x² = 18²
81 + x² = 324
x² = 324 - 81
x² = 243
x = √(243)
factor 243 to find a perfect square
x = √(3*81)
x = 9√(3)<u />
B and E are the correct answers, as 2/100 is the same thing as 0.02.
