A tree broken at a height of 5 cm from the ground and it's top touches the ground at a distance of 12 m from base of the tree fi
Harrizon [31]

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,

hypotenuse^2=base^2+perpendicular^2

x^2=12^2+5^2

x^2=144+25

x^2=169

Taking square root on both sides.

x=13

Height of tree = x+5=13+5=18\text{ m}

Hence, the height of tree is 18 m.
