21. A telecommunications company is building a third cell tower in a region with existing towers located at
A ÊÁË −2,−3 ˆ˜¯ and B ÊÁË 5,−3 ˆ˜¯ . Each unit in the coordinate plane represents 0.6 mile. They ask you to determine the
location of the third tower so that the triangle formed by the three cell towers has an area of about 10.1
square miles and a perimeter of about 15 miles, and the distance from the third tower to tower A is about 6
miles. Estimate the coordinates of the third tower to the nearest integer.
22. You are building a gazebo that has a floor shaped like a regular polygon with 8 sides. A regular polygon is a
convex polygon with all sides congruent and all angles congruent. The sum of the interior angles of a convex
polygon is 180 (n − 2)°, where n is the number of sides of the polygon. What is the measure of an interior
angle in the floor of the gazebo? Round decimal answers to the nearest tenth degree.
