Question

Tree of height 20 breaks at a point five high from the foot of the tree touching the ground at a point then the distance between the food of the tree and top of the tree is

Answer 1

if tree breaks from 5 m

and total length of tree is 20 m

then the remaining height of tree is 5m now

then tree breaks , so 20 - 5 =15 m

ie:

hypotenuse of the right angled triangle is 15 now

from , Pythagoras theorem

a^2 + b^2 = c^2

5^2+b^2=15^2

b^2 = 225-25

b^2 = 200

b = √200

b=14.14m
