Question

A man walks 5m due south and then 12m due East. Find his distance from the starting point.​

Answer 1

13 m

Explanation:

Between south direction and east direction we have right angle, so we can use Pythagorean theorem:

a² + b² = c²

a = 5 m

b = 12 m

c = the distance

`5^2+12^2=c^2\\\\c^2=25+144\\\\c^2=169\\\\c=√(169)=13\,m`

Answer 2

Answer: 13 m

Explanation:

distance from starting point = root{(5)^2 + (12)^2 }

=root{ 25 + 144}

= 13
