The equation of a circle is x2 + y2 + 4x − 2y − 20 = 0. Find:(a) the length of the tangent to this circle from the point (5, 2)
Question
Solution 1
To find the length of the tangent to the circle from the point (5,2), we first need to find the center and radius of the circle.
The general equation of a circle is (x-h)² + (y-k)² = r², where (h,k) is the center of the circle and r is the radius.
