Sue and 9 friends share half a pizza. Each piece of pizza is the same size. Sue believes each piece of pizza has an angle measure of 13°. Is Sue correct?

Sagot :

We have the total measure of the pizza is 360° if we have half of a pizza that will be

360/2=180°

If we divide the 180° between 10 people (Sue and 9 friends) in order to know the degrees per piece of pizza

[tex]\frac{180}{10}=18\text{\degree}[/tex]

as we can see each piece of pizza has an angle measure of 18° therefore Sue is incorrect
