Answer:
13.8 m
Step-by-step explanation:
Let BD represent the tree before it is broken at C
D touches the ground after it is broken at A
AB = 12m
BC = 5m
According to Pythagoras theorem
ACsq = CBsq + ABsq
AC sq = 7sq + 12sq
AC sq = 49 + 144
ACsq = 193
AC = 13.8
F. Ans The total height of the tree = 13.8 m
