The equation of a line that is tangent to a circle whose equation is x^2+y^2 = 36 and passing through the point (12, 4) areY = – 0.1742 X + 6.09 and Y = 2 X – 8.7569 it is true or false​

Answer»

Step-by-step explanation:

EQUATION of CIRCLE is x

2

+y

2

=9

equation of tangent parallel to 2x+y−3=0 is 2x+y+λ=0

its distance from centre = radius of the circle.

radius of circle =3 units.

4+1

∣2×0+0+λ∣

=3

⇒λ=3

5

∴ Equation of tangent is 2x+y+3

5

=0
