The equation of the tangent to the circle x^2+y^2-9=0 making an angle 60^ with the X -axis is

Options

  1. A1 3 x-y 6=0
  2. B3 x-y 6=0
  3. C3 x+y 6=0
  4. D1 3 x+y 6=0

Correct answer

B. 3 x-y 6=0

Step-by-step solution

Slope of tangent =m= 60^ = 3 Equation of tangent, y=m x a 1+m^2 y= 3 x 3 1+3 [ radius =3] array ll & y= 3 x 6 & 3 x-y 6=0 array

A circle touches both the coordinate axes and the straight line L 4 x +3 y -6=0 in the first quadrant. If this circle lies below the line L =0 , then the equation of that circle is 2025If the smallest circle through the points of intersection of x^2+y^2=a^2 and x +y =p, 0 < p < a is x^2+y^2-a^2+ (x +y -p)=0 then = 2025If the lines 3 x-4 y+4=0 and 6 x-8 y-7=0 are the tangents to the same circle, then the area of that circle (in sq.units) is 2025Circles are drawn through the point (2,0) to cut intercepts of length 5 units on the X -axis.
