Q. 139

Height of a pole is 8 m. Find the length of rope tied with its top from a point on the ground at a distance of 6 m from its bottom.

Answer :

Given: Height = 8m

Base = 6m

Formula Used/Theory:-

Pythagoras theorem:-

Base2 + Height2 = Hypotenuse2

Hypotenuse is length of rope tied on top of pole to ground

(Length of rope)2 = 82 + 62

(Length of rope)2 = 64 + 36 = 100

Length of rope = √100

= 10cm

Result:- Length of rope is 10cm
