Question

A man goes 12m due south and then 35m due west. How far is he from the starting point. 

Answer 1

 

In right triangle SOW
By using Pythagoras theorem, we have 

`OW^2=WS^2+SO^2` 

=`35^2+12^2`  

=`1225+144`  

=`1369` 

`∴ OW^2=1369` 

⟹ 𝑂𝑊 = 37 𝑚
Hence, the man is 37 m away from the starting point.
