A person walks 20m to east, 50m to north and 15m at 75º from north to east.
What's the total distance from the origin the person walked ?

My answer ~64,0m

Is the answer correct ?

y=15 cos75º y=3,9
x=15 sin75º x=14,4

50m to north + 3,9m = 53,9
20m to east + 14,4 = 34,4


(53,9)² + (34,4)² = D²
sqrt(4095) ~ 64m
