A skier started skiing from the position (-1.732, 1.939), measured in kilometers, and skied counter-clockwise for 1.82 kilometers, where he pavaed for a brief rest. (Consider the circle to be centered at the origin). Determine the ordered pair (in both kilometers and radii) on the coordinate axes that identifies the location where the acier rested. (Hint: Start by drawing a diagram to represent this situation.) (, y) =( > radii (x, y) = ( Dilometers Points possible: 10 Unlimited attempts.

for his initial position ,angle with positive x axis , i=- tan-1(1.939/1.732)
let for his resting position position ,angle with positive x axis be r
length of arc =radius *angle in radians
=>1.82=2.6*(r -i)
=>(r -i) =1.82/2.6
=>r =i+(1.82/2.6)
=>r =- tan-1(1.939/1.732) +(1.82/2.6)
=>r =2.999866 radians
=>r =171.88o
(x,y) =(cos171.88o ,sin171.88o)radii
(x,y) =(-0.990,0.141)radii
(x,y) =(2.6cos171.88o ,2.6sin171.88o)kilometers
(x,y) =(-2.574,0.367)kilometers
please rate if helpful. please comment if you have any doubt
