so 9 times 8 is 72 so 155-72=83 and 83 divided by 6 equals 13.8333 but you can’t have .8333 delivery’s so you round it up to 14 so he needs to make at least 14 delivery’s to reach his goal of 155 delivery’s
A 30° angle is measured 30° counterclockwise while a -30° angle is measured 30° clockwise. Therefore, you can say -30°=360-30°=330° because 30° is a reference angle located in Quadrant IV.
