Question

I really don’t get this.

Answer 1

75+ 84+138+135+108 = 540 altogether , or it is going to be 360⁰ on a pie chart.

(75/540)*360 = (75*360)/540= 50⁰ = A.
(84/540)*360= (84*360)/540 = 56⁰ = B.
(138/540)*360 = 92⁰ = C.
(135/540)*360 = 90⁰ = D.
(108/540)*360 = 72⁰ = E.

50 +56 +92 +90 + 72 = 360⁰
