Suppose you were north for 35 kilometers then travel east 65 kilometers. How far are you from your starting point? North and east can be considered the directions of the y and x-axis respectively. Round to the tenth's place.
\n" ); document.write( "If you were to draw the lines of your travel, you'd make a right triangle with
\n" ); document.write( "one leg=35km
\n" ); document.write( "another leg=65km
\n" ); document.write( "The hypotenuse of the right triangle would be the distance from the origin, which is your starting point.
\n" ); document.write( "The Pythagorean Theorem is $\"highlight%28c%5E2=a%5E2%2Bb%5E2%29\"$ , where c=hypotenuse and a,b are legs.
\n" ); document.write( " $\"c%5E2=35%5E2%2B65%5E2\"$
\n" ); document.write( " $\"c%5E2=1225%2B4225\"$
\n" ); document.write( " $\"c%5E2=5450\"$
\n" ); document.write( " $\"sqrt%28c%5E2%29=sqrt%285450%29\"$
