Answer:
Explanation:
For students getting an A there are 5 out if 90 total. 5/90 is the fraction getting an A. The pie chart will be a whole entire circle, which is 360°.
So,
For A: 5/90(360) = 20°
For B: 15/90(360) = 60°
For C: 40/90(360) = 160°
For D: 20/90(360) = 80°
For E: 10/90(360) = 40°
Drawing the accurate pie chart, well, here's a tip-- remember you know what 90° looks like. In half, that's 45° or in three pieces its 30° . A straight line is 180° so use these guides and grow or shrink the angles to get the approximate sizes you need (20°, 60°, 160°, 80°, 40°)
