Question

tree is broken by the wind but does not separate if the point from where it breaks is 9 metre

above the ground and its top touches the ground at a distance of 12 metre from its foot find out

the total height of the tree before it broke
​

Answer 1

Step-by-step explanation:

Let ACB be the total length of the tree broken AC+BC=9m

Let height of BC=hm

Then CD=CA=9−h

sin30•. = BC/CA

1/2 = h/9-h

2h = 9-h

2h + h = 9

3h = 9

:. h = 3 metre

hence at 3 m from the bottom the treenis broken.
