What horizontal distance has she covered?

ANSWER
169.1m
EXPLANATION
From the diagram, the horizontal distance traveled is x meters.
This is the side adjacent to the 6° angle.
Since we know the hypotenuse to be 170m, we use the cosine ratio to find the value of x.
[tex]\cos(6 \degree) = \frac{opposite}{hypotenuse} [/tex]
[tex] \cos(6 \degree) = \frac{x}{170} [/tex]
.
This implies that
x=170cos(6°)
x=169.0687222
To the nearest tenth, the horizontal disance travelled is 169.1m
