  1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
  2. Wait patiently for a helper to come along.
  3. Once someone helps you, say thank you and close the thread with:
    +close
    
  4. Feel free to nominate the person for helper of the week in #helper-nominations
  5. Do not ping the mods, unless someone is breaking the rules.
  6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

I'll use one for an example

#

Let's say that School, Flower shop, and bank are a triangle (which they are)

#

The distance from the bank to the flower shop, which is "a" in the pythagorean theorem, is 25

#

The distance from the bank to the school, which is b in the theorem, is 30.

#

That means the distance from the school to the flower shop squared is 30^2 + 25^2.

#

Square rooting that will give you your answer.

#

sqrt(30^2 + 25^2)

#

Do that for all other 7 questions

#

If School to Post Office is 75, and post office to church is 15, what is school to church?

#

Then do the same thing you did with school -> gas station

faint relic
#

but how

#

can you explain it to me

cyan badger
#

Which part?

#

For school -> gas station, you do the pythag theorem but reversed

faint relic
#

really?

cyan badger
#

Let's use the school -> Gas station

#

(School to Gas station)^2 + (Gas station to Post Office)^2 = (School to Post Office)^2

#

We know what gas station to post office is and what school to post office is

#

(school to gas station)^2 + 25^2 = 75^2, as we replace gas station to post office and school to post office

#

So school to gas station is sqrt(75^2 - 25^2)

#

You can apply that formula to school to church

faint relic
#

ok i got 70.7

#

Now do the same thing for school->fire station

#

(school to fire station)^2 + (fire station to church)^2 = (school to church)^2

cyan badger
#

So let's pretend school to fire station is "x". I'll write that because its difficult to write the entire thing

#

The fire station to church is 30 yards

#

The school to church is equal to the school -> post office + post office -> church

#

That means school -> church is 75 + 15

#

x^2 + 30^2 = 90^2, as 75 + 15 = 90

#

x^2 + 900 = 8100

#

Tell me if you need more help
