A) The graph is misleading because it dosent give the number of students, it gives percentages.
b) A more appropriate way to display data would be a line graph because it shows the number of students favorite sports.
Angle in a semi circle is 90°
<a = 180-90-<b = 90-28 = 62°
opposite angles of a cyclic quadrilateral sums up to 180°
<b + <a = 180
<b = 180-62
<b = 118°
