Question 147048
Yes, you are right it does have to do with a triangle.
By the way. Orginoally is spelled wrong. Orginally.

Here's water surface ------------------------------------------------
The water lily plants was 10 inches above it so. Imangine this:

                                  I <-water lily
                                  I
-------------------------------------------------------------------------
Chris then rode the boat 5 feet, As i imangine they are in the middle. Chris would go 5 feet away from the lily.
                                 I
                                 I
                                               V <- Chris and Pat.
----------------------------------------------------------------<-water surface.
So. If this forced Pat ( person holding the lily that was still remained rooted to the depth.) to touch the water.
It would look like.     _______________________ <- 5feet.  
A triangle. with the .. I  <- 10 inches.       . 
                        I                     .  
________________________I____________________.________________<-water surface.
                                            .                                                                              .                                                                              .                                                                              .           
So evuantally(sp?) you will get a triangle, and then, you get the equation of the Pythagorean Theorem. which. a=10inches. and b=60. so.
a(squared)+ b(squared)=c(squared).
You can do the rest?
100+360=c(squared).
460=c(squared)
somewhere around 21.45. is the depth . I think.
