Question

i) A tree Is broken by the wind but does not separate. If the point from where It breaks Is 12 metre above the ground

and its top touches the ground at a distance of 5 metre from its foot , find out the total height of the tree before it

broke.​

Answer 1

This is an example of Pythagoras triangle (right angle triangle).....

It will be -

The height after breaking - 9 M.

The base or the distance - 12 M.

Now the fallen part or the hypotenuse - x

We know a^2 + b^2 = c^2

Here, a=9, b=12 and c is x...

So, 9^2 +12^2 = x^2

: 81+144=x^2

: 225=x^2

: x = √225

: x = 15

The height before its breaking = 15 M. + 9 M. = 24 M.

Hope it helps! :-)

i got it from somewhere mate
