Answer 1

Answer:

11........................

Answer 2

Answer:

5m

Step-by-step explanation:

Let us consider a Cartesian plane thinking positive X-axis as South,

Negative x axis as North, Positive Y-axis as East and Negative as West.

A man walked along negative X-axis 3 m and then parallel to negative Y-axis he walked 2 m.

And then parallel to negative X-axis he walked 1 m and finally walked 5 m parallel to positive Y-axis and he has coordinates of (−4,3).

He makes right angle triangle with base AC=4, side AB=3 and hypotenuse BC.

∴ by Pythagoras theorem,

BC ^2 =AB ^2 +AC ^2

⟹ BC ^2 =3 ^2 +4 ^2

∴ BC=5.

Hence from origin he is at distance of 5 m.

Thus, option A is the correct.
