 Hello and welcome to the session, I am Deepika here. Next, this is the question which says, A tree breaks due to the stone and the broken part bends so that the top of the tree touches the ground making an angle 30 degrees with it. So this is between the foot of the tree to the point where the top touches the ground is facing itself, point the height of the tree. Let us first understand the trigonometric ratio of the angle C in the right triangle ABC. Now, in right triangle ABC is equal to side opposite to angle C upon hypotenuse that is AB upon AC is equal to adjacent to angle C upon hypotenuse that is BC upon AC and is equal to opposite to angle C upon side adjacent to angle C that is AB upon BC. So this is the key idea behind our question. We will take the help of this key idea to solve the above question. Let's start the solution. First, let us draw a simple diagram to represent our problem. Here, BC represents a tree which breaks and the broken part AC bends so that the top of the tree C touches the ground making an angle 30 degrees with it. Now, the distance between the foot of the tree to the point where the top touches the ground is 8 meter. So we have a triangle ABC, right angle at B. Now, given BC is equal to 8 meter, angle BAC is equal to 30 degrees. We have to find the height of the tree that is we have to find AB. Now, to determine AB, we choose a trigonometric ratio which involves both AB and BC. We will choose a trigonometric ratio 1030 or cot 30 because as the ratio involves AB and BC. Now, to determine AB, we choose a trigonometric ratio which involves both AB and BC. So we will choose a trigonometric ratio 1030 or cot 30 as these ratio involves AB and BC. So in right triangle ABC we have BC upon AB equal to 1030. Now, BC is given to us 8 meter so we have 8 upon AB is equal to now cross multiplying we get AB is equal to 8 root 3 this implies the height of the tree is 2 3 meter. Hence the answer for the above question is 8 root 3 meter. I hope the solution is clear to you. Bye and take care.
