Let's do this question the top of a broken tree touches just the ground at a distance of 12 meter from
its base.
If the tree is broken at a height of five meters from the ground, then the actual height of the tree
is already owns the video.
Give it a try and then let's do it together.
All right.
We're back.
I hope you've given it a try over here.
Let's draw the diagram of this Work-Based based problem.
It's mentioned that the tree is broken at five meters from the ground, so this length over here is
five meter and it touches the ground at a distance of 12 meters from the base.
But this is the base.
So this is very touching the ground.
So this distance over here is 12 meters.
Now, this is a right angle triangle, right?
Because this angle over here is a 90 degree angle because trees make a 90 degree angle with the ground.
All right.
So let's take this side over here.
As X as per Pythagoras's theorem, we know that X Square is equal to five square plus 12 square.
That's twenty five plus one 144, which is equal to one sixty nine.
Therefore, X is equal to square root of 169, which is equal to thirteen.
Right now.
We need to find the height, the actual height of the tree.
Right.
You might be tempted to immediately option B as the answer, but we have not yet arrived at the answer
that actual height is equal to five plus 13.
Right.
Which gives you 18 metre.
That's the initial height of the tree.
And your correct answer is option C, that is 18 metre.
