## anonymous one year ago Julie is looking at a treasure map. The map is marked in paces. If she is standing at the streetlight, how many paces will it be for her to go directly to the bridge?

So, each square represents a pace?

3. anonymous

yup

4. Owlcoffee

Let's create a triangle using the paces we need. First off let's take 7 paces to the left and then about 5 up, and we want to find the hypotenuse of the triangle: |dw:1436194791651:dw| $x^2 = 5^2 + 7 ^2$

74

6. Owlcoffee

Close, what you just calculated was this: $x^2=74$ Now, taking the square root on both sides: $x = \sqrt{ 74}$

7. anonymous

8.6

8. Owlcoffee

Correct.

9. anonymous

its not an option but the closest are 7 and 10

10. Owlcoffee

I would say the answer is 10.
