The eucalyptus tree, perpendicular to the ground, breaks and bends in such a way that its apex touches the ground, forming an angle of 30 ° with the ground. The distance between the top of the tree touching the ground and the trunk of the tree is 12.11 meters. Find the length of the tree.

Answer:
Here, AC represents the tree when erect,
and BD represents the broken part of the tree
while BC represents erect (remaining) tree.
DC is the distance between the top of the tree and the base of the tree.
∴ ∠C=90

,BC=5 m, AC=15 m,
BD=AB=AC−BC=10 m
Now, sinθ =
