A ladder rests against a wall so that its top touches the roof of the house. If the ladder makes an angle of\[{{60}^{o}}\]with the horizontal and height of the house be \[6\sqrt{3}\] meters, then the length of the ladder is
A)\[12\sqrt{3}\]
B)12 m
C)\[12/\sqrt{3}\,\,m\]
D)None of these
Correct Answer:
B
Solution :
Length of ladder = \[\frac{6\sqrt{3}}{\sin {{60}^{o}}}=12\,m\].
