Question

Filiz is walking at a bearing of 300°. When she has traveled 20 meters, how far west from her starting point is she? Round to the nearest tenth.

Answer 1

She is 10m west of her starting point

Answer 2

She is 17.32 m west from her starting point.

Explanation:

The arrangement is given in the figure below.

We need to find xy value.

∠yxz = 90 - (360-300) = 30°

We have xz = 20 m

`cos30=(xy)/(xz)=(xy)/(20)\\\\xy=17.32m`

She is 17.32 m west from her starting point.
