Answer:

\frac{360}{n}

Step-by-step explanation:

Given:

The above statements

Required

Complete the above statements

Considering the third statement in the question;

First, it should be noted that a circle is a full sector that measures 360 degrees

Assuming the circle is divided by a central angle of 180, the number of sectors formed will be;

\frac{360}{180} = 2\ sectors

Further assume the circle is divided by a central angle of 90, the number of sectors formed will be;

\frac{360}{90} = 4\ sectors

Similarly, if the circle is divided by a central angle of n, the number of sectors formed will be;

\frac{360}{n}

Hence, from the list of given options; \frac{360}{n} fills the gap correctly
