Question 1089687
A pie chart is circular. Right? So, a circle is 360 degrees. Add up the sectors you know: 25+45+90 = 160; then 360-160 = 200 and 200/2 = 100, we have 2 sectors each 100 degrees.
------------------------
28000/25 = 1120
1120*45 = 50400 is allocated to the 45 degree sector
1120*100 = 112000 is allocated to one of the equal sectors (100 degree sectors)
