The equation of the tangent to the ellipse x^2+16 y^2=16 which makes an angle 60^ with the X -axis is

Options

  1. A3 x-y+7=0
  2. B) 3 x+y+7=0
  3. C3 x+y-7=0
  4. D3 x-y=0

Correct answer

A. 3 x-y+7=0

Step-by-step solution

Equation of tangent to the ellipse x^2 16 + y^2 1 =1 , have slope m= 60^ = 3 is aligned & y= 3 x 48+1 & 3 x-y+7=0 or 3 x-y-7=0 aligned
