Explanation:
total number of people are 40
take teach takeaway category and divide it by 40
eg)3÷40 / 11÷40
since there are 360⁰ in a circle, multiply your answer by 360 to get your angle
(3÷40)×360 = a
(11÷40)×360 = b
(9÷40)×360 = c
(2÷40)×360 = d
(15÷40)×360 = e
those are your angles. use a protractor to measure the angles
note : if all your angles add up to 360 the you've done everything correctly
