Question

A man starts from his office and goes 4 km northwards, and then he turns left and goes 3 km and reaches a point 'X'. At what distance is
he from the starting point?​

Answer 1

Explanation:

USING THE PYTHAGORAS THEOREM,WE SEE THAT,

A^2 + B^2 = C^2

4^2 + 3^2 = C^2

16 + 9 = C^2

C = √25

C = 5.

SO, HE IS 5 KM FROM THE STARTING POINT.

Answer 2

Answer:

5 km

Explanation:

ac =

$\sqrt{ {ab}^{2} + {bc}^{2} }$

ac=

$\sqrt{ {3}^{2} + {4}^{2} }$

ac=

$\sqrt{9 + 16}$

ac=

$\sqrt{25}$

ac= 5 km

Therefore at a distance of 5 km he is from the starting point
