Suppose you travel north for 35 kilometers 
then travel east 65 kilometers. How far 
are you from your starting point? North and

       |        B=65     .
       |             .
   A=35|         .   
       |    .     C 
       |

C² = A² + B²

C² = 35² + 65²

C² = 1225 + 4225

C² = 5450
      ____
 C = Ö5450

 C = 73.8241153

Round to the tenth place:

 C = 73.8
