yehi h iska correct ans

Answer 2

Answer:

Let A’CB be the tree before it broken at the point C and let the top A

′

touches the ground at A after it broke. Then ΔABC is a right angled triangle, at B.

AB=12 m and BC=5 m

Using Pythagoras theorem,

In ΔABC

(AC)

=(AB)

+(BC)

=(12)

=144+25

(AC)

=169

AC=

169

AC=13 m

Hence, the total height of the tree(A

B) =A

C+CB=13+5=18m.
