A hiker walks 200m west and then walks 100m north. What is the magnitude and direction of her resulting displacement?

A hiker walks 200 m west and then walks 100 m north, the resulting magnitude is 223 m. The direction can be solve using trigo function sin angle = opposite / hypotenuse. Which is equal to 26.6 degree. So the displacement and direction is 223 m 26.6 degree North of west.
