Question

How far from the skydiving center did Stella land?

Answer 1

Answer: 1.67 kilometers.

Step-by-step 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:

$cos(\alpha)=\frac{adjacent}{hypotenuse}$

3. Substitute values and solve for $x$:

$cos(37)\frac{x}{2.1}\\x=(2.1)[cos(37)]\\x=1.67$
