Suppose you first walk 7.5 m in a direction

`20.0\deg `

west of north and then 17.5 m in a direction

`40.0\deg `

south of west. Part (a)

`✓`

How far are you from your starting point in meters?

`R=16.53m`

`✓`

Correct! Part (b) What is the angle, in degrees, of the compass direction of a line connecting your starting point to your final position measured south of west?

`\theta =14.70\deg ,`

Correct!

`\theta =14.70\deg `

Part (c)

`✓`

Repeat part (a), but for the magnitude of the displacement in meters for the second leg where you walk 17.5 m in a direction

`40.0\deg `

north of east.

`R=21.24m,✓`

Correct! Part (d) Repeat part (a), but now you first walk 7.5 m in a direction

`40.0\deg `

south of west and then 17.5 m in a direction

`20.0\deg `

east of south.

`R^('')=`
