You can put this solution on YOUR website! a runner runs 5 miles, then turns 65 degree to the left and runs 5 more miles. what is the runners total distance traveled? what is the total displace?
----------
Start Point:: (0,0)
End Point:: (x,y)
Total x displacement:: 5 + 5cos(65 degrees) = 7.11 miles
Total y displacement:: 0 + 5sin(65 degrees) = 4.53 miles
-----
Total distance traveled :: 10 miles
Total displacement = sqrt[4.53^2 + 7.11^2] = 8.43 miles
