Help plsss Which of the following is an equation of a circle in the xy-plane with center (1, 2) that has a radius with an endpoint at (-5, -6)?
A) (x - 1)^2 + (y-2)^2 = 100
B) (x - 1)^2 + (y-2)^2 = 10
C) (x+1)^2 + (y + 2)^2 = 100
D) (x+1)^2 + (y + 2)^2 = 10

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
