AP EAMCET · Maths · Straight Lines

If the straight line passing through \(P(3,4)\) makes an angle \(\frac{\pi}{6}\) with the positive \(x\)-axis in anticlockwise direction and meets the line \(12 x+5 y+10=0\) at Q , then the length of the segment PQ is

  1. A \(\frac{64}{12 \sqrt{2} 1}\)
  2. B \(\frac{96}{9 \sqrt{2}-1}\)
  3. C \(\frac{112}{10 \sqrt{3}+3}\)
  4. D \(\frac{132}{12 \sqrt{3}+5}\)

Answer & Solution

Correct Answer

(D) \(\frac{132}{12 \sqrt{3}+5}\)

Step-by-step Solution

Detailed explanation

Any line through \(P(3,4)\) making an angle with \(x\)-axis is \(\frac{x-3}{\cos 30^{\circ}}=\frac{y-4}{\sin 30^{\circ}}=r\) Any point \(Q\) on it is \(\left(\frac{r \sqrt{3}}{2}+3, \frac{r}{2}+4\right)\) and \(Q\) lies on \(12 x+5 y+10=0\)…
