engineering mathematics MCQ #1839

  1. Question 1

    Q1. The angle between the lines 2x + y = 1 and x - 2y = 3 is

    • A) 90°
    • B) 60°
    • C) 45°
    • D) 30°

    Answer: 90°

    Explanation: Using angle formula: tanθ = |(m1 - m2) / (1 + m1*m2)|, where m1 = -2, m2 = 1 / 2, so tanθ is undefined, hence θ = 90°
