Question

siddu travelled 5 km towards East and from that point 12 Kms towards north how far is he now from the starting point​

Answer 1

Pythagoras theorem,

$\sqrt{5 {}^{2} + 12 {}^{2} }$

=13km

Answer 2

In triangle ABC

LET AB=12m and BC=5m

Find AC

BY PYTHAGORAS THEOREM

(AC)2=(AB)2+(BC)2

=(12)2+(5)2

=144+25

=169

(AC) 2=√169

AC=13

SO, HE IS 13m far from the starting point
