Ответ:
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;
Further assume the circle is divided by a central angle of 90, the number of sectors formed will be;
Similarly, if the circle is divided by a central angle of n, the number of sectors formed will be;
Hence, from the list of given options;
fills the gap correctly
