Question 71745
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.
If you were to draw the lines of your travel, you'd make a right triangle with 
one leg=35km 
another leg=65km
The hypotenuse of the right triangle would be the distance from the origin, which is your starting point.
The Pythagorean Theorem is {{{highlight(c^2=a^2+b^2)}}}, where c=hypotenuse and a,b are legs.
{{{c^2=35^2+65^2}}}
{{{c^2=1225+4225}}}
{{{c^2=5450}}}
{{{sqrt(c^2)=sqrt(5450)}}}
{{{c=73.8241153}}}
{{{highlight(c=73.8km)}}}
Happy Calculating!!!!
