## Elementary Geometry for College Students (6th Edition)

The rocket is $\approx 866$ ft in the air after 5 seconds.
1. Find the value of x using the sine law $\frac{x}{sin60} = \frac{200}{sin90}$ $x = \frac{200sin60}{1}$ $x = 173.2050....$ ft/s 2. Multiply the x value by the number of seconds asked by the question (In this cause, the question is asking the height of the rocket after 5 seconds) Let $H =$ Height of the rocket after $5$ seconds $H = 173.2050... \times x$ $H = 173.2050... \times 5$ $H = 866.0254...$ $H \approx 866$ ft
