Question

a man walks 5 km south and then 3 km towards towards west. find how far is he from the starting point​

Answer 1

Answer:

A man walks 5km south and 3 km west

hence, the distance from starting point = hypotenious side

Let the hyotenious distance be x

Therefore, by problem-

x² = 5² + 3²

or x² = 25 + 9

or x = √25 + 9

or x = 5 + 3

hence, x = 8
