Question 35581
Three students are standing at different places on the playground.  Sally is at the swings and Jimmy is 5 feet belowo her at the see-saw.  kathy is 12 feet left of Jimmy at the jungle gym.  How far is Kathy form Sally?  (hint: draw a picture first.)

Yes, draw the picture.  You should get a right triangle.
One side is 5; the second is 12.
Let the third side be "x".
Using Pythagoras you get:
x^2= 5^2 + 12^2
x^2= 25+144= 169
x=13 feet (distance Sally is from Kathy)
