What is the tangent equation that touches the circle x2 -y2 -8x -16y -209 equals 0 at the point of 21 and 8 on the Cartesian plane?
Point of contact: (21, 8)
Equation of circle: x^2 -y^2 -8x -16y -209 = 0
Completing the squares: (x-4)^2 +(y-8)^2 = 289
Centre of circle: (4, 8) and its radius is 17
Slope of radius: 0
Slope of tangent: 0
Tangent equation of the circle: x = 21 meaning that the tangent line is parallel to the y axis and that the radius is parallel to the x axis.
