3. Darcy mounted a motion sensor so it would light a path to the door on her deck. If you know AB = 10 feet, and BE and BD trisect ZABC, what is the
perimeter of the deck area to the right of the beam of light (ABDC)?
A
E
D
10ft.
Z
В
motion
sensor
Part 1: What other angles or sides of ABDC can you label given that side AB
is 10 feet, BE and BD trisect ZABC? Label the diagram accordingly, and
explain your reasoning. (4 points)
