Step-by-step explanation:
Michael owns a small paper company called Michael Scott Paper Co. He has 5 clients and needs to sell them each a specific amount of paper. They have each ordered 3 3/10 worth of boxes. He has to find out how many paper boxes he has to sell and how much extra paper (in tenths) he has total.
IF you want to turn it into a question, add:
How many paper boxes is he selling?
X=40 degrees because it s on the circle. arc AD+arc DC=180 arc DC is 100 so AD is 80. That means x must be 40.
