Avery can explain to her school principal that 85% of juniors think there is a lot of homework because several indicators have increased.
<h3>What is an indicator?</h3>
An indicator is a datum that is taken as a reference to analyze the evolution or change of a fact over time. In this case, the indicators would be:
- Weekly hours used to do homework
- Number of students with work for after school.
According to the information, it can be inferred that 85% of Junior students consider that there is an increase in homework because there were the following changes compared to last year:
- Increase in hours spent on after school homework, last year the average was 5 hours, this year it is 8 hours.
- Increase in the number of students with after school jobs, last year it was 135 students, this year it is 215 students.
From the foregoing, it can be inferred that the number of homework has increased in Junior students and that is why now 85% of them consider that homework has increased.

Answer:
x = 135°
Step-by-step explanation:
The angle x is the same fraction of 360° that the shaded area is of the area of the circle.
The area of a circle is given by the formula ...
A = πr²
For a radius of 12 cm, the area of the circle is ...
A = π(12 cm)² = 144π cm²
Then the measure of angle x is ...
x = (54π cm²)/(144π cm²)×360°
x = 135°
