TS EAMCET · Maths · Straight Lines
If the normal drawn from the origin to the straight line \(2 x+7 y+6=0\) makes an angle 0 with the positive \(X\)-axis, then \(0=\)
- A \(\tan ^{-1} \frac{7}{2}\)
- B \(\pi-\tan ^{-1} \frac{7}{2}\)
- C \(\pi+\tan ^{-1} \frac{7}{2}\)
- D \(\tan ^{-1} \frac{7}{2}\)
Answer & Solution
Correct Answer
(C) \(\pi+\tan ^{-1} \frac{7}{2}\)
Step-by-step Solution
Detailed explanation
Given equation of straight line, \(2 x+7 y+6=0 \Rightarrow \frac{x}{-3}+\frac{y}{-6 / 7}=1\) So, angle \(\theta=\pi+\angle A O M\)…
