Question

What horizontal distance has she covered?

Answer 1

169.1m

Step-by-step 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) = (opposite)/(hypotenuse)`

`\cos(6 \degree) = (x)/(170)`

.

This implies that

x=170cos(6°)

x=169.0687222

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