Question

What horizontal distance has she covered?

Answer 1

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.

$\cos(6 \degree) = \frac{opposite}{hypotenuse}$

$\cos(6 \degree) = \frac{x}{170}$

.

This implies that

x=170cos(6°)

x=169.0687222

To the nearest tenth, the horizontal disance travelled is 169.1m
