The angle between the lines (2 x+11 y-7=0 ) and (x+3 y+5=0 ) is

Options

  1. A( ⁻¹ ( 17 13 ) )
  2. B( ⁻¹ ( 4 35 ) )
  3. C( ⁻¹ ( 1 7 ) )
  4. D( ⁻¹(7) )

Correct answer

C. ( ⁻¹ ( 1 7 ) )

Step-by-step solution

Given lines (2 x+11 y-7=0 ) ( gathered and x+3 y+5=0 m₁=- 2 11 , m₂=- 1 3 = | m₁-m₂ 1+m₁ m₂ |= 1 7 = ⁻¹ ( 1 7 ) gathered )
