The first figure has 3 line segments.
the second figure has 3+3 =3*2 = 6 line segments
the third figure has 3+3+3 = 3*3 = 9 line segments
the fourth figure has 3+3+3+3=3*4=12 line segments...
so it is clear that:
the 20th figure has 3*20=60 line segments.
Answer: 60
(x+1)^2 +(y-1)^2 =9
x+ the x coordinate squared + y +the y coordinate squared = the radius squared
X is 1/4
2/3 X 1/4 = 1/6 make all have the same bottom number to make it easier
8/12 x 3/12 = 2/12
