A) \[\pi /4\]
B) \[\pi /6\]
C) \[\pi /3\]
D) \[3\pi /4\]
Correct Answer: D
Solution :
Midpoint of the line joining the point \[(4,\,-5)\] and \[(-2,\,9)\] is \[\left( \frac{4-2}{2},\,\frac{-5+9}{2} \right)\] i.e. (1, 2). \Inclination of straight line passing through point (-3, 6) and midpoint \[(1,\,2)\] is \[m=\frac{2-6}{1+3}=\frac{-4}{4}=-1=\tan \theta \] . Þ \[\theta =\frac{3\pi }{4}\].You need to login to perform this action.
