<h3>3 Answers: B, C, F</h3>

Each of these are closed figures formed by straight line segments. Think of fencing in an area (not necessarily a rectangle) using various straight fence sections. The length of each section does not have to be the same.

Side notes:

Choice A is not a polygon because the figure is not closed.
Choice D is not a polygon because it is not composed of line segments only. Choice D is an ellipse instead.
Choice E is not a polygon due to the curved portion.

Imagine right triangle with first leg to be the Chad length and second leg to be the Chad's shadow. Second leg has length 14.3 ft and since t<span>he straight-line distance from the top of Chad’s head to the end of the shadow creates a 23° angle with the ground, you could consider the trigonmetric function
</span>
$\tan 23^{\circ}= \dfrac{\text{Chad's length}}{\text{Chad's shadow length}}$ ,

then $\tan 23^{\circ}= \dfrac{\text{Chad's length}}{14.3}, \\ \text{Chad's length}=14.3\cdot \tan 23^{\circ}=6.1$ .<span />
