Question

Find the equation of tangent to the circle x^2+y^2=144,from the intersection point of lines 3x+4y=36 and 4x+5y=20?

Answer 1

Step-by-step explanation:

The above circle has center at (1,3) & radius 2.

Let tangent passing through the point (−1,2) be drawn at the point (h,k) on the circle: x2+y2−2x−6y+6=0 then the point (h,k) will satisfy the equation of circle as follows.
