A) \[0{}^\circ \]
B) \[30{}^\circ \]
C) \[45{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: D
Solution :
The lines are \[\frac{x}{3}=\frac{y}{2}=\frac{z}{-6}\] and \[\frac{x}{2}=\frac{y}{-12}=\frac{z}{-3}\] Since, \[{{a}_{1}}{{a}_{2}}+{{b}_{1}}{{b}_{2}}+{{c}_{1}}{{c}_{2}}=6-24+18=0\,\,\Rightarrow \,\,\theta ={{90}^{o}}\].You need to login to perform this action.
