Straight Line Question 2
Question: The angle between the lines $ y=(2-\sqrt{3})x+5 $ and $ y=(2+\sqrt{3})x-7 $ is [MP PET 1997]
Options:
A) $ 30^{o} $
B) $ 60^{o} $
C) $ 45^{o} $
D) $ 90^{o} $
Correct Answer: B $ \theta ={{\tan }^{-1}}( \frac{2-\sqrt{3}-2-\sqrt{3}}{1+4-3} )={{\tan }^{-1}}(-\sqrt{3})=-60^{o} $ Considering smaller angle $ {\theta }’=60^{o} $ .
