A) \[10\text{ }m\]
B) \[\sqrt{3}\text{ }m\]
C) \[5\sqrt{3}\text{ }m\]
D) \[10\sqrt{3}\text{ }m\]
Correct Answer: D
Solution :
Let the length of broken point (BC) = x. In \[\Delta \,ABC,\] \[\cos \,{{30}^{o}}=\frac{15}{x}\] \[\Rightarrow \] \[x\times \frac{\sqrt{3}}{2}=15\] \[\Rightarrow \] \[x=5\sqrt{3}2=10\sqrt{3}\,m\]You need to login to perform this action.
