If It is in fact (b), then it's 90 degrees
a) To find amount collected in each category - you must understand that the numbers inside the circle represent an angle (in units of degrees).  Since we know a circle is composed of 360 degrees, we know each other portions as a ratio of that full circle

for simplicity sake, i will use "d" to represent "degrees"

Shirts = (140d)/(360d)*($7200) = $2800
Pants = (80d)/(360d)*($7200) = $1600
Other = (75d)/(360d)*($7200) = $1500
Shoes = (360d - 140d - 80d - 75d)/(360d)*($7200) = $1300
Total = $7200 [OK]

b) Knowing long sleeve shirts are to be 1/4 of the shirts sales, find the angle which represents in on the pie graph:

angle (long sleeve shirts) = 1/4*(140d) = 35d

c)  Assuming ratios to maintain over the next $900 of sales

Pant sales (in the next $900 of total sales) = ($900)*(80d/360) = $200
