Question

Find the equation of tangent to circle x player + y squared minus 4 x + to buy equals 20 vichar perpendicular to the line nextplus to buy + 4 = 20

Answer 1

The distance of the tangent from the centre is

∣∣∣3(1)−4(2)+c32+42−√∣∣∣(c−55)2

(c−5)2−152(c−20)(c+10)

c=3=32=0=0=20or−10

The required tangents are:

3x−4y+20=0or3x−4y−10=0

Hope this helps you ☺️☺️✌️✌️❤️❤️
