It's Pythagorean Theorem:

A boot leaves port and travels 18 miles north and 15 miles east. How far from port is the boat?

I have drawn a picture, 15² + 18² = c²

²= squared.

Thanks... meh

please someone help mewith this, thanks.

  • Pre-Algebra -

    225 + 324 = c^2
    549 = c^2
    take the square root of 549.
    c = 23.4
