She is 10m west of her starting point
Answer:
She is 17.32 m west from her starting point.
Step-by-step 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
6, 9
y1-y2 over x1-x2
slope formula ^^
90
2
6x3 = 18
4x3 = 12
18 - 12 = 6
16 / 4 = 4
6 - 4 = 2
