So the story continues...

Days came and passed. None of the night sleeps resulted in a dream to 
take him to the 13th century with the now ready table. So at night, when 
warming himself with a little fire and getting ready to go to his 
sleeping bag, he thought to himself, "If I don't travel back to Maragheh 
observatory tonight, I'll just burn the one page table in the fire and 
forget about it."

The night became morning, and Physfit still in his sleeping bag openned 
his eyes and realized something was not right. There were clouds above 
him! "At this altitude?..." he asked himself. He turned his head left 
and found he was looking at urban areas of Dallas, with the Reunion 
Tower over there standing by downtown! Turned his head right and saw 
that he was lying down in his sleeping bag at the top of a 100 yard 
mountain, with his house in the view, within a short walking distance! 
He quickly, before anything get changed again, got up and put on his 
mountain shoes and dress, and got ready to climb down fast before the 
mountain gets bigger again.

By the time he reached the ground level, it was 4:45 pm and the sun was 
setting, and in another 15 minutes he was home, at his computer, going 
through the news.

He read somewhere that at least half of the Americans' missiles to hit 
Houthi targets would only hit the adjacent areas, not the targets 
themselves, but each time Houthis lauched a missile, it came down dead 
correct and hit the target. Physfit wondered about it for a few moments.

There were a few related news pieces as well. In one of them, from a 
Pakestani press outlet, they explained in detail how the missiles 
automatically calculated the coordinates of the target. A reconnaissance 
drone beforehand would get near enough to target to see it, then using 
laser would fly on a straightline towards the target and record its own 
coordinates at two different points on that straight line.

Then using such information, back home, the distance of the target to 
the missiles launching site would accurately get calculated. Then they'd 
launch the missiles.

Everything calculated were in two dimensions only. Just height and the 
distance.

If the drone calculated coordinates of the two points on that line of 
sight as (x_1, y_1) and (x_2, y_2), with x being the distance and y the 
height, then the distance of the target to launch area would have any of 
the two forms below:

     x  . y  - x  . y
      1    2    2    1
x = -----------------
          y  - y
           2    1

or:


          /x  - x \ . y
          \ 2    1/    1
x = x  - --------------
      1       y  - y
               2    1


And the Americans in charge being cro-magnons (and Nazi), seeing that 
one of the above formulas can be derived from the other one, were 
assuming it didn't matter which one to use for calculating x-intercept 
for their missiles to hit Houthis targets. But Houthis, being Modern 
Humans, always chose one of the above, and never the other.

So Physfit found out why about half of American missiles narrowly miss 
their targets, while Houthis missiles always hit the targets.

1- Verify that the two formulas are correct, and algebraically related.

2- Assuming the drone calculated (x_1, y_1) as (1.31, 4.76) kilometers, 
and (x_2, y_2) as (1.93, 3.24) kilometers, and assuming that for 
shortest computation time, numbers are rounded to three digits in the 
codes imbedded in drones and missiles, then calculate the x-intercept in 
both ways.

3- Explain which of the two methods is being used by the Houthis, and why.
