Step-by-step explanation:

8a-20b-28-6a-9b-15

2a-29b-43

The coordinates of a circle with radius 1 are (cos(theta), sin(theta))
(-3,1) designates a circle with radius radical 10, as 3^2+1 = 10, square root of 10 is radical 10
thus the coordinates are (2cos(theta), 2sin(
-3=2cos(theta), -3/(10^0.5) is cos(theta)
1 is 2sin(theta), 1/(10^0.5) is sin(theta)
tangent is sin(theta)/cos(theta), or -1/3
