Answer:
The original height of tree is 18 m.
Step-by-step explanation:
Consider the correct question is "A tree is broken at the height of 5m from the ground and its top touches the ground at a distance of 12m from the Base of the tree. Find the original height of the tree."
A tree is broken at the height of 5m from the ground.
Let the height of the tree is (x+5) m.
After broken, it will form a right angle triangle with hypotenuse x, base 12m and perpendicular 5 m.
Using Pythagoras theorem,




Taking square root on both sides.

Height of tree = 
Hence, the height of tree is 18 m.
