21. A store wants to mount a security camera to record video of the door and the cash reg- ister. The best non-moving cameras can be equipped with lenses that will cover a specific angle--an angle of up to 180°. The camera will be mounted 30 ft from the door and 20 ft from the cash register. If the door is 15 ft from the cash register, what angle must the camera cover to watch both sites? Include a diagram.

The Census Bureau Web site gives several choices for "average income" in its historical income data. In 2006, the median income of American households was $48,201. The mean household income was $66,570. The median income of families was $58,407, and the mean family income was $77,315. The Census Bureau says, “Households consist of all people who occupy a housing unit. The term ‘family’ refers to a group of two or more people related by birth, marriage, or adoption who reside together.” Identify the reason for mean incomes for households being higher than median incomes for households.
