Answer:
To calculate the size of the serving angle A in the diagram of the volleyball court, you can use trigonometry.
You have the following information:
The distance from point A to point C is 9 meters.
The distance from point A to point B is 31 meters.
To find angle A, you can use the inverse tangent (arctan) function:

Rounded to the nearest degree, the size of the serving angle A is approximately 73 degrees.
Step-by-step explanation:
Sure, I'll explain it in a simpler way:
Imagine you're standing at point A on the volleyball court, and you want to serve the ball towards point C or point B. Point C is 9 meters away, and point B is 31 meters away from you.
To find out how wide the angle is between where you stand (point A) and where you want to serve the ball (between points C and B), we can use a special math trick. It's like saying, "How much do I need to aim to the left or right?"
We use something called "arctan" to figure it out. When we do the math, we find that the angle A is about 73 degrees. So, you need to aim your serve at about a 73-degree angle to get the ball between points C and B on the other side of the court.

Step-by-step explanation:
Answer:
1666.7 minutes
Step-by-step explanation:
To find out how many minutes it takes to fill the pool, you can use the formula:
Time (minutes) = Total volume / Flow rate
In this case, the total volume of the pool is 15,000 gallons, and the flow rate is 9 gallons per minute.
Time (minutes) = 15,000 gallons / 9 gallons per minute
Time (minutes) = 1,666.67 minutes (rounded to two decimal places)
So, it takes approximately 1,666.67 minutes to fill the pool.
