Ex 5.2, 2 (ii) Find the central angle of each sector. Total Votes = 90 + 120 + 150 = 360 Fraction = (𝑁𝑢𝑚𝑏𝑒𝑟 𝑜𝑓 𝑉𝑜𝑡𝑒𝑠)/(𝑇𝑜𝑡𝑎𝑙 𝑉𝑜𝑡𝑒𝑠) ∴ Central angle of summer = 90° Central angle of rainy = 120° Central angle of winter = 150° We follow the steps 1. Draw a circle of any radius. Mark Radius as OA. 2. Put protractor on AO and Draw largest angle 150° 3. Now, put protractor on AO and Mark angle 90° 4. The remaining portion is 120° 5.
