The pie shows in for pupils 200-100 divided by 7 ks3 Ana’s is 5
F(-1)=1-2=-1
f(4)=16-8-4=4
A(x)=f(4)-f(-1)/4-(-1)
A(x)=4-1/4+1=3/5
You can see that the section that contains the angle is exactly 1/3 of the circle. The answer to A is 1/3 because the circle is divided into 3 equal pieces. Now for B, since the total measure of a circle is 360°, divide that by 3 to get the measure for the given angle. 360 divided by 3 is 120, so the given angle is 120°
