Triangle CDA is the image of triangle ABC after a 180-degree rotation around the midpoint of segment AC. Triangle ECB is the image of triangle ABC after a 180-degree rotation around the midpoint of segment BC. Explain how to use what you know about the sum of the angles in a triangle to figure out the sum of the angles of quadrilateral ABED. *

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x
