Ron lives 6 miles due north of the ball field, and Stan lives 8 miles due west of the ball field. What is the straight line distance between their homes? (It makes a right triangle.)
You would use Pythagoras' theorem (a^2 + b^2 = c^2) because it is a right-angled triangle. 6^2 + 8^2 = 36 + 64 = 100. √100 = 10. So your answer is 10 miles, I hope this helps!
