Question 142017: Town A is 5 miles east and 7miles south of town B how far apart are the two towns?
Answer by jojo14344(1513)   (Show Source):
You can put this solution on YOUR website! We use pythagorean theorem.
7miles south of town A to B will be your vertical line ------ mark "a"
5miles east of town A to B will be your horizontal line ------- mark "b"
Distance from town A to B will be the diagonal line ---------- mark "c"
So,
c^2 = a^2 + b^2
C^2 = 5^2 + 7^2
c^2 = 74
c= sq rt 74
c=8.6 miles
*note: it's true that going east is horizontal and going south is vertical.
North to South is vertical line, and west to East is horizontal line.
Thank you,
Jojo
