Let A'CB represents 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, right angled at B.
AB=12m and BC=5m
Using Pythagoras theorem, In ΔABC
(AC)² +(AB)² +(BC)²
⇒(AC)² =(12)²+(5)²
⇒(AC)² =144+25
⇒(AC)² =169
⇒AC=13m
Hence, the total height of the tree=AC+CB=13+5=18m.
