Find the 5

Find the equation of the circle with the center at (1,20), which touches the line 8x+5y-19=0

Correct answer:

e : e: (x-1)^2+(y-20)^2 = 89

Step-by-step explanation:

x0=1 y0=20  8x+5y19=0  s=8 x0+5 y019=8 1+5 2019=89 a=82+52=899.434 r=as=9.43489=899.434  (xx0)2 + (yy0)2 = r2 e:e:(x1)2+(y20)2=89=89:1
