6 feet = 1 fathom, so 36,198 ft = 6,033 fathoms

A league has a variety of definitions. Variation is not only country-to-country, but also by land and sea, and by use in fiction (20,000 Leagues Under the Sea) and non-fiction. At sea, it is generally taken to be 3 nautical miles, which is now defined in SI units as 5556 meters, or 18,228.34645669... feet.

Using Google as the unit converter to leagues, the depth is about ...

... 1.99 leagues.

From where Kiana is standing, she must look up at a 50° angle to see the top of a building. If she backs up 50 feet, she will ne
Morgarella [4.7K]
For this case, what we must do is solve the following system of equations:
 tan (50) = h / x
 tan (40) = h / (x + 50)
 Solving the system we have:
 (x + 50) * tan (40) = h
 (x) * tan (50) = h
 Matching:
 (x + 50) * tan (40) = (x) * tan (50)
 Rewriting:
 x (tan (50) - tan (40)) = 50 * tan (40)
 x = 50 * tan (40) / (tan (50) - tan (40))
 x = 118.9692621
 Substituting:
 h = (x) * tan (50)
 h = (118.9692621) * tan (50)
 h = 141.7820455
 Answer:
 
The height of the building is:
 
h = 141.7820455 ft

How do you write an equation for (-5,-1), (0,-1)
lesya692 [45]
Both the points have a coordinate where y is -1, so the equation is simply -1

y=-1

however if you wanted to really show the working out, it looks like this:

y=mx+c

m=change in y/change in x

m=(-1-1)/(-5+0)=0

subsitute one of the coordinates into y=mx+c

-1=0+c

c=-1

so then y=-1
