You walk 50 m to the north, then turn 60° to your right and walk another 45 m. How far are you from where you originally started?

well if you start 50 m Due South of the North Pole,it makes a very interesting problem. Think on that.
Now anywhere else,
result= 50N+ 45sin60 E + 45 cos60 N
then combine the like directons, and the distance will be given by the distance formula
distance= sqrt (xN^2 + yE^2) where xN is the north distance, and yE is the east distance 
63 m
