A) \[20\text{ }meters\]
B) \[10\sqrt{3}\text{ }meters\]
C) \[10\text{ }meters\]
D) \[10\sqrt{2}\text{ }meters\]
Correct Answer: C
Solution :
Let \[AB=x\text{ }m\] be the remaining part of the broken tree AC, From right angled \[\Delta \,ABC,\] \[\sin \,{{30}^{o}}=\frac{AB}{BC}\] or \[\frac{1}{2}=\frac{x}{20}\] \[\therefore \] \[x=10m\]You need to login to perform this action.
