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.
Answer:
81
Step-by-step explanation:
3 digits ^4 number options

b. 12
c. 10
d. 11
The formula works out to D. 11
We are given the values of the variables so we can rewrite the formula as:
= a2 + 3b ÷ c - 2d
= 3² + (3 × 8) ÷ 2 - (2 × 5)
= 9 + 24 ÷ 2 - 10
At this point, PEMDAS then kicks in where division will be done before subtraction and addition. Then the first operation between addition and subtraction will be done:
= 9 + 24 ÷ 2 - 10
= 9 + 12 - 10
= 21 - 10
= 11
In conclusion, the value of the above formula comes out to 11.

There are 5 row and 8 tiles in each row calculated using two equation.
Simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
Given I am an array made with 40 tiles I have an odd number of rows and an even number of tiles in each of my rows the number of my rows plus the number of tiles in each of my rows equals 13
Let "r" be the number of row and "t" be the number of tiles in each row.
Since, array has total 40 tiles
Thus,
r * t = 40
Also given
r +t = 13
From comparing these equation
r = 5 or 8
Since row is odd given
thus, r = 5
and t = 8
therefore, Two equations are used to determine the five rows and eight tiles in each row.
