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?

Answer 1

X = 45*cos60 = 22.5 m.
Y = 50 + 45*sin60 = 89.0 m.

D = sqrt((22.5)^2+(89)^2) = 91.8 m.

Answer 2

Correction:

X = 45*cos30 = 38.97.
Y = 50 + 45*sin30 = 72.5 m.

D^2 = (38.97)^2 + (72.5)^2 = 6774.91
D = 82.3 m.
