AP EAMCET · Maths · Straight Lines

A straight line is drawn through the point \(A(1,2)\) such that its point of intersection with the straight line \(x+y=4\) is at a distance \(\frac{\sqrt{6}}{3}\)
from the given point ' \(A\) '. Find the angle which the line makes with the positive direction of \(X\)-axis.

  1. A \(\theta=15^{\circ}\) and \(75^{\circ}\)
  2. B \(\theta=75^{\circ}\) and \(45^{\circ}\)
  3. C \(\theta=45^{\circ}\) and \(60^{\circ}\)
  4. D \(\theta=60^{\circ}\) and \(30^{\circ}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\theta=15^{\circ}\) and \(75^{\circ}\)

Step-by-step Solution

Detailed explanation

Let the angle of inclination of line \(\theta\), and as passed through point \(A(1,2)\), so equation of line is \(\frac{x-1}{\cos \theta}=\frac{y-2}{\sin \theta}= \pm \frac{\sqrt{6}}{3}\) \(\therefore\) General point on the line is…
