When both poles are together (x = 0), the cable is 10m off the ground (y = 10)
This is what makes the difference: when both poles are 80 m away (x = 80) the cable is 50m off the ground (y = 50)
So it is a linear relationship with these points:
x=0, y =10 and x=80, y=50
interpolating, we get these points:
x=0, y=10
x=20, y=20
x=40, y=30
x=60, y=40
x=80, y=50

Answers:
a) when the cable is 20m off the ground (y=20), the poles are 20m away (x=20)
b) when the cable is 10m off the ground (y=10), the poles are next to each other (x=0)

Plus, Nicaragua is not exactly a pacific country.

So, let me get this straight, the military relies on Google Maps to define their borders, and they take action on it. That's BS, if you ask me. ... or perhaps, evil Google is cooking the WW3?

I wonder what Venezuela's Hugo Chavez might be saying: "The Empire is making these two brother countries fight each other!"
