Q. 113
Jiya walks 6 km due east and then 8 km due north. How far is she from her starting place?
Answer :
Given: 6km in east
8km in north
Formula Used/Theory:-
When jiya moved from east to north it possess 90° angle
And the distance of position to his home will be hypotenuse
And form an right angled triangle
⇒ Pythagoras theorem:-
side2 + side2 = Hypotenuse2
As 8km and 6km are 2 sides of right angled triangle
Then;
82 + 62 = Hypotenuse2
Hypotenuse2 = 64 + 36 = 100
Hypotenuse = √100
Hypotenuse = 10km
∴ jiya is 10 km from his house
Result:- Jiya is 10 km from his house
