Question

How far from the skydiving center did Stella land?

Answer 1

Answer: 1.67 kilometers.

Explanation:

To solve this problem you must apply the proccedure shown below:

1. You have a right triangle, as you can see in the figure attached, where the angle is 37° (
`\alpha`), the hypotenuse is 2.1 and you can call
`x` the distance between Stella and the skydiving center, which is the adjacent side of the triangle.

2. Therefore, you have:

`cos(\alpha)=(adjacent)/(hypotenuse)`

3. Substitute values and solve for
`x`:

`cos(37)(x)/(2.1)\\x=(2.1)[cos(37)]\\x=1.67`
